I'm probably going to get blasted because I haven't read much theory, I am but a pleb. Still, here's my take:
Value would be synonymous with importance. Value is determined by how important something is for humans' well-being, and as we know: value is dependent on situation. People would get their share of necessities and luxuries to the extent it is possible considering sustainability. When well-being is taken care of, having even more of initially important things may not always make sense, and hoarding and stealing would not be necessary. At first these things will probably need to be controlled, but as society gets used to the absence of competition enforcing these things may end up unnecessary. As for personal property value I'll use myself as an example: I want to breed fish and propagate corals, have an orchard and brew wines, ciders, meads, and beers, run a composting facility. So it would make no sense for me to live in a city or the suburbs ,and I would probably not get the best patches of farmland either as I'd mostly produce luxuries and not necessities. And I'd be fine with it, and I would request a general area I'd like to live in and I'd probably work things out with a local council or something, idk…
Of course. But why would people not work? Capitalism, feudalism, and all previous societal models have made work a necessary evil, a chore we need to do in order to survive. Work in capitalism symbolizes our lost freedom. Capitalism has perverted our natural tendency to be creative and make things, physical or theoretical. Work has become our enemy, and brainless entertainment has become the savior. Under socialism we would be more free to choose people could finally start to work because they want to work, because they want to contribute, because they want to create, without the burden of worrying about earning enough money. Also, robotics and automation will be even more important.
You harvest more grain than you need. I make more bread than I need. The workers at Miele make more ovens than they need. The professors at university enriches your view of all reality. Scientists make new things possible. These things are shared, no one is exploited, everyone benefits.
Capitalism has entrenched itself by, among other things, making us loathe work and thereby thinking working for "free" completely idiotic. Not working for money does not mean you work for free, you work for the mutual benefits of all of society.
Theoryautismos: I'd appreciate comments on this.
