Indentured servitude is slavery you smooth brained moron, it just has contractual terms of release, in historic cases.

Quite a bit of lolbertarian imbecility coming out as soon as their "buildings roads is slavery" dogma is challenged. No, indentured servitude is not slavery, as you cannot control someone's life, kill him for no reason, as you can with slaves.

If the state provides all of my needs but offers zero opportunity for upward mobility or the ability to leave, I am effectively a serf which is effectively a slave.

A serf isn't effectively a slave either. So much historical ignorance from our lolbertarians.
