Always lots of fascinating stuff here and I know I’m playing catchup, so just bear with me:
Joe and Bob agree to a contract in which Joe agrees to provide Bob a service and Bob agrees to pay Joe. Joe provides the service. Bob welches. Joe hires people to extract the contracted amount from Bob by force (or alternatively, Joe’s protective force performs this service for him).
Is there debate about whether that is a violation of the NAP?
From my earliest days of being a Libertarian, it’s always felt like “fraud” was this redheaded stepchild tacked on to the end of libertarianism as an afterthought, and I’ve never quite grokked its relationship. The NAP I get, and of course I get that fraud - specifically, the breaking of contracts - is an undesirable thing, but I’ve never been able to see the link between fraud and a justification for violence. And yet, if I’m understanding some of the AnCap literature correctly, I think they advocate that this is a perfectly acceptable use of violence (note I’m purposefully avoiding the use of the term “initiation of force” here since in a lot of ways, that’s really the question: is Joe initiating the force, or is he simply responding with force legitimately to Bob’s fraud?)
I have to say that while I can see why Joe would be tempted to use force - he’s mighty pissed and he wants his freaking money that he earned fairly! - I still don’t see how a society in which violence is used in this situation is better than one in which it isn’t. Surely, there have to be alternatives, e.g. buy some freaking contract insurance upfront from a simple actuarial insurance company (splitting that upfront cost with Bob, of course); reputation systems will develop that will more than punish Bob sufficiently for his breach of contract (e.g. who will ever sign a contract with him again?); before entering into a contract with someone you don’t know well, get some sort of “deposit” from them;etc.
The more radical way of putting this is: it almost seems to me like the NAP isn’t enough. It’s not enough to simply say “don’t initiate force”. We advocate this because we think it would make a better world for us. But I want more than that. I want a peaceful world, one in which the only justification for violence is immediate self-defense from the same. No “defensive first strikes”. No “retaliatory violence because through your violence, you have said that you accept violence” (my poor paraphrase of Rothbard). Some of the AnCap literature seems to go to some lengths to justify violence that is far, far from an immediate self-defense need, and the resulting vision of society is… not one that I think I like as much as a more peaceful alternative.
And, fwiw, I think some of those visions are really, really hard sells with the general populace. A desire for peace is a surprising ubiquitous thing.
