But fundamentally, I don't see how the "American"-libertarian tradition of the non-aggression principle and homesteading principle are necessarily supportive of landlordism and bossism, since it ultimately depends on what action and time is considered to be sufficient for homesteading and abandonment of property.  For example, even the most hard-core anarcho-capitalist will admit that if you leave you home abandoned for a long enough time, that it will eventually be considered abandoned and thus homestead-able by new parties or the current renters.
