I understand your view King Hazza, but the point is that everyone is an individual and society is not a creation of government, it is individual ideas that create society, that is what is private property rights, just as human rights; it is the based on the principle of ethical conduct and simple rules and guidelines that are formulated on the natural order or things; Epistemological or leaned things ; That is why you have a computer , food house etc , it did not be create from an Ideological presupposition to exist because it does , be it but by individuals who created these things , not by superstition based on Ideological metaphysical mysticism.
The word public is an anathema in political terminology; it is a substitute word for Individuals who make society, who create society and the things you have today; human interaction, that is how it is and not politics Omniscient fantasy ; there lay the paradigm .

But the fact is, infrastructure is *rightfully* the property of the sum of its users (the public);
As such, it is most ideally placed in public control, be it through a direct-democratic system, or failing that, an authority that answers to public votes.
The alternative- allowing it be privately owned, creates a vastly stronger and less accountable monopoly

Well if it is a business then the whole Idea is to provide services to the consumer, products and services, the owner will have engaged in the most productive and efficient means possible; one is to raise capital to service and update the mechanisms that may be deployed to sustain such a business; and on the other hand as you have noted; Airport, You are by compulsion to pay what the owner demands, and in a some , Sydney Airport is the most expensive and inefficient Airport in the world ;
Who can compete? No One.
Then we look at the Electricity market ; My example in Japan , and systematically the same model exists worldwide;
But Australia, our network was built on Tax dollars, in turn becomes a safe Haven for Political exploitation and a cash cow, over many years moneys have been stolen by political parties and used for their own gains at the expense of the entire Collective who depend on the network are now compelled to pay exorbitant and ridicules and inflated costs; Now add corrupt philosophy of environmentalism and extortion.
Again this is the Political Means ; Theft and Predation.
If that was a private business , totally free of Government intervention who had conducted their business like that , then expect a lot of people would be convicted of some serious fraud charges; and of course the collapse of the business; Not so with Government, they Just raise the cost and compel the people as Collective to pay More and More and More until ; Who can afford it? No one; Who can compete with it ? No one ,
And that is not providing services on a free market for consumers
And who is ever held accountable for their criminal conduct ? No One.
And that is the collective society in retrogression

It still remains that it would remain the same for any entity controlling the same assets would be in the exact same position to charge a compulsory fee to 'use' the service. As the asset is a vital entity that people can't afford not to use regardless of how badly the service is provided (Telstra, Sydney Airport, Qantas, Lane Cove Tunnel, Sydney Ferries, power supply etc), the only thing the owners of these assets need to do is impose costs where they can get away with, and people will be forced to pay for them knowing that alternatives aren't really accessible. It doesn't matter whether they are a government enforcing default power or a private company that merely bought it- once they own it they gain default power to rip off the people that use their asset.

The only difference is how accountable that entity is to the public, which at the moment is either
1- governments- which are hardly accountable at all- but being in their possession means the asset is also liable to be improved when a better party or stronger government-regulating legislation or constitutional entries are placed, or of course, when democracy in the country actually starts to increase and publics get more of a say (our main parties do NOT like this notion- but at the end of the day they will be forced to accept this if such a vote or party passes through.
2- a private business, which is not accountable to the public at all (being the whole point a business is supposed to be private after all), and by being in their possession will remain their personal property until either the business is forced to sell it or relinquish it.

The problem with the theory of collectivism is in a sense oxymoronic ; there is not a singular doctrine , nor ever a doctrine that could ever work especially when the basis of such Ideology is based on a bias that does not measure to ratiocination , but is enforced by thuggery force and compulsion ;
It well contradict your Ideas of what is Collectivism, but you must realise that there is near three hundred years of Social experimentations; You can simply read or listen to any books written in the early eighteenth century; from France – Germany- England etc, etc where you will learn that democracy is nothing other than that form which in principle was the realm of the Monarch, but is the final centralisation of Power –
Look at it this way, common conspiracy theory in regards to Masons – etc and the Icon such as the Pyramids in Egypt;
In the evils of the Ideological they see that the Egyptian Empire of those days is the premise of which society be ordered ; It not be an Icon of achievement , but that of the perfect State , the Statism of servitude of its people to serve the elite classes who consider themselves the divinity of omniscience.
Democracy and the Majority rule , as it was in the Greek days , as it was in the Roman days , as it was in Germany asserts the eventual collapse of societies as Political and its own people plunder society as if it is their divine right to violate the Rights of Individuals and personal property to usurp it for their own gains; We can see why there is collapse
We cannot disregard historical fact because it does not fit the Idea of a Chimera as the bate to rob people of their own reasoning ability.

Now you are trying to imply what "democracy" is by referring to monarchical systems (Germany under the Kaiser?)
Let alone to imply Athenian democracy, Roman Democracy, Westminster, (and by insinuation, Swiss)?

And even trying to bring in Masonic conspiracy theories!

This just gets more entertaining by the minute;
I'm not even having to do anything to help!

It would be, if anything, more probable, if I were to compare libertarianism to the current system of governance in Somalia.
