In an ideal world, to my mind at least, we wouldn't need to worry about ownership because everybody would have enough respect to consider that others have the right to make use of everything too and curtail their own use to what is necessary instead of using in excess. Unfortunately this isn't an ideal world, so it's no surprise when people want to be able to keep what they've worked for, especially when the example they see is what it currently is.

In some ways it probably comes down to tolerance levels. Why begrudge ownership if that's what someone feels they need to survive, as long as it causes no harm or impact on others? The hard line to draw is where that starts to impact others. If someone had a belief that capitalism/communism/ socialism is the way for them, then who am I to judge as long as it doesn't impact me or others? My issue is when others feel that their way needs to be forced onto everyone else. I agree that voluntaryism is probably the closest description we do have to a live and let live situation.
