Ah, trademark laws and patents are obviously governmental stuff. So - not present in some imagined absolute capitalism. And with those abolished (except for stealing authorship still being illegal), I suppose market mechanisms would do their job sufficiently well for this particular case.

Believing in capitalism is believing in humans making rational and moral choices, anyone to do that would be nuts. That's a proactive answer to politically active people getting triggered by my comment and labeling me as a member of the other crowd.
