I’ll offer a guess. But it’s not in the hypothetical Libertopia. I don’t know where that is.
It’s in the real world, where this sort of stuff happens all of the time. And with a reasonable minimum of government influence. So it’s probably not a bad approximation of what most libertarians would settle for, if they could move the needle on American government in the right direction.
You have breached a contract. You haven’t said whether you have admitted that or not, or how willing you are to contest it, or whether you are willing to go to arbitration. I’ll assume for the moment that you aren’t contesting it, and you’re sitting on your front porch, cleaning your shotgun saying ‘Come and get me, suckas’ to your neighbors.
First, I don’t think any Libertarian would ever argue that a citizen has the right to use force to compel another citizen to do anything, regardless of what a written contract says. There are basic rights enshrined in the Constitution that are not trumped by private party contracts. If the expectation was otherwise in the mind of either party when they entered into the contract, they were either naive or stupid.
Writing good contracts is as much a part of effective transactions in a libertarian society as theoretical (and potentially comic-book) remedies of relief such as ‘forcing someone to volunteer’. An intelligent homeowner’s association contract would spell out remedies for relief if you decide not to volunteer.
The homeowner’s association couldn’t force you to move. That would also require some sort of coercive action, potentially involving bodily harm. I am also assuming they don’t have any claim on your home - it’s your asset, they don’t own it, so they have no legal claim to it.
An intelligent contract would have some remedy of relief built in. Maybe you place an at-risk deposit in escrow. Maybe a fine of $5000 levied by the homeowner’s association. If you default on the fine, there are established collection laws and judicial precedents for dealing with those things. And yes, at the end of a long and tortuous route, if you don’t have the money, a sheriff can force the sale of your home to pay it and boot you out onto the street. But I think that would take a while.
Bottom line…if you have serious assets at stake: your home in this instance, fire protection in the homeowner’s associations’ instance, think about how to draw up intelligent, enforceable contracts into which both parties will willingly enter, with reasonable remedies for relief spelled out in advance. No Libertarian would advocate some ridiculous remedy of an unreasonable contract.
