Left-libertarianism

Unlike most versions of egalitarianism, left-libertarianism endorses full self-ownership, and thus places specific limits on what others may do to one's person without one's permission. Unlike the more familiar right-libertarianism (which also endorses full self-ownership), it holds that natural resources[…]may be privately appropriated only with the permission of, or with a significant payment to, the members of society.

This is in line with what we know of [John] Carpenter’s political attitudes, which on balance veer towards a kind of post-60s left-libertarianism.
