(I part ways with Rothbard here. While hereditary slavery is more debatable, I don't have a problem at all with selling yourself into slavery. For me, a contract is an enforceable promise; removing my option to make enforceable promises cannot benefit me. If you don't want to make the promise, don't sign the contract. And promising to be your faithful servant so long as you and I shall live is a perfectly normal, legitimate, and (in a sane world) common sort of promise.)

I admit it: I am a pronomian. I endorse the nomos without condition. Fortunately, I do not have to endorse hereditary slavery, because any restoration of the nomos begins with the present state of possession, and at present there are no hereditary slaves. However, if you want to sell yourself and your children into slavery, I don't believe it is my business to object. Try and strike a hard bargain, at least. (A slightly weakened form of pronomianism, perhaps more palatable in this day and age, might include mandatory emancipation at twenty-one.)

And there is, of course, http://unqualified-reservations.blogspot.com/2009_03_01_archive.html which cannot be excerpted and done proper justice.
