[Would a so-called "Free State" allow indentured servitude?]
No, Roscoe.
Indentured servitude is entered into by contract. You just rejected Libertarian "principle."
Your rant seems to be more with the concept of a Libertarian party, which is a faction, rather than the concept of a soveriegn state. Do you have an arguement against the states rights vs the federalist as articulated by the FSP. I am signed on to the FSP as a Republican not a Libertarian.
Are you a Federalist?
