Well, in that case, you can answer your own question, simply by recalling how you yourself learned it.
Well maybe it's not really Capitalism? I could analyse my own experiences without any discussion, make some conclusions and stick to them, but then there's no feedback, no quality control, no fresh ideas...
Then you're not using logic. Scarcity is not a requirement for desire. I desire knowledge, yet knowledge is not scarce.
I also like knowledge, but it seems that I can never have it all. As an analogy for rights, would that mean our 'ability' to have rights is somehow constrained? I see the difference but how is it relevant?
By addressing him, you are saying he "owns" his argument. You are also "owning" your fingers and mind to formulate the argument. Arguing against self-ownership always self detonate in this way.
If you could slow down for a second... I'm trying to get to the bottom of this 'Capitalism' thing from first principles. The Lemming humans (from the OP) are being bombarded with new ideas:
Ownership? What's that?
Property? What's that?
Did the concepts exist before anyone "put pen to paper" or made sounds to describe them for the first time? Can a 'concept' be a law of nature? Or were the concepts created by people? They couldn't create themselves -- that would be paradoxical.
