The idea that you can "own" something beyond neccesary personal property like a house...
So you can legitimately "own" a house? Then that means you can legitimately "own" the land on which the house sits. And you can likewise "own" the wood - and thus, the trees - from which the house was made. You're admitting that exclusive claims of land resources for the benefit of one individual is legitimate - and even "necessary." This contradicts your anti-property theories.
And capitalism is not evil, but it is a system of structural oppression...
I suppose if you see property as evil (which you obviously do not, since you think private ownership of land resources is "necessary"), then you'll naturally think that using such property for financial gain is "structural oppression." Does it matter to you if this "capitalism" actually improves the living conditions of those who participate in the economic system? Or do you only see the relative "poorness" of certain people as proof of its shortcomings, regardless of why those people are relatively poor compared to others? Do you only fault "capitalism" for all of the poorness, or do you look at other factors that may be causing it?
Property is not "natural" it is a modern invention ,and it's the basis of capitalist structural oppression.
Modern, as in, just the last couple of centuries? Or modern, as in, since the dawn of "modern" civilization? And are we talking about "property," or are we talking about the nonsensical attempt to distinguish "personal" property from "private" property? I'm not a communist, so I don't make such absurd distinctions about claims of ownership.
My toothbrush is mine, whether I only use it myself, or let my friend use it for a nickel per brush when needed. I don't instantly become an evil oppressor when they need to clean their teeth and don't have any other way to do it, do I? Or should I just let everyone who needs a toothbrush use mine until its destroyed, then use my own time and labor to acquire a new one for myself to use - and for everyone else who needs to use it as well? Maybe they should get their own toothbrush or fairly compensate me for using and wearing down mine?
