I'm confused. What is the difference from giving it to someone else or abolishing private property? If my dad's farm is taken away from him, what happens when some other person decides they want to do something else with it? Will the government decide that instead of his 3 ponds he dug and built on the land himself, they should instead be turned into land fills? What if they decide he should instead switch his cropland to something else, or ask him to level his black walnut trees that he has been growing on his farm for 30 years for more farmland?
Again, how will you get him (or me, or my kids) to give up that land so someone that has never spent any time there can decide how it is used? Are you just relying on education so that we think it will be a good idea?
There's this constant thought of something being 'taken away', but that's not the right way to think about it. We've been bred under modern capitalism to think of objects, land, toys, chewing gum, whatever, as being strictly under the ownership of someone. Almost every single object or thing, in nature or otherwise, right now is
ownedby some person or entity, even airspace. But this doesn't really mean anything and is mostly illusory conceptions applied by humans, and although very useful and needed conceptions at this time, all it gives you is exclusive access or use to that object or thing at your whim. Under scarcity, this ownership makes sense (getting into the whole rights at production is a separate issue) because if there's only one stick of chewing gum, and since I have the most money, I can appropriate for myself this gum.
In socialism and on the road to real communism, you
need to own less and less. It doesn't make sense to
owna piece of land under communism because there's no real reason anyone would claim such a ridiculous notion of 'owning the land' to begin with: you don't need exclusive access to the thing. Sure, in the earlier stages of socialism, it will still make some social relational sense to keep this conception alive, like I said the road is long, just as feudalism paved the way for capitalism, so too does capitalism pave the way for socialism, socialism into communism.
You mention your dad has walnut trees on his property. Maybe someone else wants to plant apple trees. Yes, absolutely that is an issue to resolve. But the resolution to that issue, under communism, will be solved differently than who has the slip of paper saying they 'own' the land to plant it on. Communism is just as much of a psychological shift as it is an economic one, just as any major turning point in human society is - and this one would be the biggest (and the most fulfilling of human potential).
You can't and look at current property rights and apply a communistic perspective on them. You have to look at a much bigger picture, the picture of human history, by looking at where we
would beright before the transition to communism. That's not an easy thing to grasp by no means.
