So in an anarcho-capitalistic society what do you do if ...

You are with a couple of people and one guy says he'll give you something if you do something, you do the thing and come back for his end of the contract.

He refuses and won't hold up his end what do you do?

I'm posting this here because it's the only place i can right now. Working towards getting out of the newbie restrictions after lurking here for a long time : /

I'd like to buy 1600 US Microsoft Points (usually $20 USD) for 1 BTC

reply here or pm me

 if i don't get this resolved in a few day I'll probably forget about this thread
