At some level, private property is an invention of the State. Without that, the property belongs to whoever can defend it, and whoever has the most guns wins.
This becomes even more significant with the advent of intellectual property, also an invention of the State. There are many digital examples of "everything belongs to everyone" that are going extremely well, and luckily with zero government tyranny required. Meanwhile, the patent system is a mixed bag at best: sometimes promoting/reward innovation, sometimes inhibiting/punishing it. I don't know how this balance should be struck between sharing and ownership, but I know that the way we're handling it now is deeply sub-optimal.
The concept of ownership and the ways in which we trade are social constructs, the economic "rules of the road". They are malleable, not inherent, and we can rewrite those rules however we wish to manage externalities such as worker safety or environmental damage. Obviously, if it is done poorly (or disingenuously), the results will not go well. But we take for granted the times when it does go well.

I'll look into this. I'm definitely a proponent of the social contract occurring at a more local level, where people are actually people instead of numbers in a database. But I'm skeptical that it is enough sustain this thing we call civilization. Just because people can be rational and altruistic does not mean they will.

There is an element of truth to this; many European entitlements go too far and cost too much (as has often happened with American unions as well). But I don't buy that social programs are inherently inefficient; there are many things that matter which don't show up on balance sheets. Stress, health, environment, social bonds, self-determination, respect: these things all matter to a society's quality of life and its bottom line, but are very hard to measure or draw profit from.
Also, we must look at the other side of the historical coin: turn-of-the-century America, where industry held all the bargaining power, and the whole family had to work 60+ hour weeks in dangerous factories with no human rights protections. Or, workers who lived in "company towns", in a life one step away from indentured servitude. I have a hard time not seeing strong similarities between Amalgamated Warehouse Whatever and the Dickensian hellscape of a century ago (or Foxconn, for that matter).
I suppose I just don't like dogma: MARKETS GOOD, GOVERNMENT BAD. The common thread between democracy and capitalism is to lessen the corrupting influence of power by distributing it: one person = one vote, and every person wielding their own power over buying and selling. But there is no system that is immune from manipulation and corruption; the incentive to game the system and maximize one's own power to the detriment of others will never go away. If we want to prevent tyranny, we have to constantly evolve ways to distribute power again, whether it takes the form of markets, governments, communities, or new organizational patterns we haven't thought of yet.
