An attack upon Lockean right to absentee ownership. No. It is not mine, though I do think it is challenging.
As for the original question about second homes, I think the basis of any property system must rest simply upon the right of human beings to engage in ongoing projects with material things. This principle is similar to the “mixing your labor” principle in that labor is usually a part of an ongoing project, but the “ongoing project” principle covers both the ideas of initial appropriation and abandonment. That said, the idea of “ongoing projects” is vague, just like the idea of “mixing labor” - but its vagueness is a strength in that it avoids the slide into rigid moral absolutism. With regards to second homes, the claim that the second home is part of an ongoing project is quite reasonable. It’s a bit less reasonable than the claim to the first house, but it’s not nearly as absurd as claiming unused land. As long as they regularly maintain both houses, they’ve shown by their actions that the houses are part of their ongoing projects.
However, I think it’s a relevant point to add that there are 1 billion squatters in the world, but much few second-home owners. Even if mutualism means that no one can own a second home (and even that claim is suspect,) I think the billion squatters of the world have much higher moral priority.
Even so, the more pertinent question is not whether one can own a second home, but what happens when the owner of two homes decides to rent the second one out. There, to me, the answer is clear - the home belongs to the tenant, and the previous owner has simply received a rental contract - which is subject to social approval/disapproval by the boycott process I described above. One could say that the act of renting out the house is an “ongoing project,” but this leads to a paradox - if the owners had simply left the house sit there without maintenance or use for years, then it would fall back into the unowned domain even by Lockean standards. But if they rent it out, they not only get rent money - they get an extension of the time for which they can claim to own the house without using it! This seems like nonsense - they keep their property because they charged money for it.
For this reason, I propose the principle that property applies to ongoing projects with things, while contracts apply to ongoing projects between people. The claim that collecting rent from the house is an ongoing project is true, but it’s an ongoing project between people. The tenant, on the other hand, can claim to have an ongoing project involving the house itself. In my last post I went over some consequentialist reasons why contracts shouldn’t be violently enforced. Now, I offer a moral argument - to enforce a contract the same way one enforces property is to treat people like things, to treat people as means to an end. If people are ends in themselves, they should be able to terminate the contract at any time…they should not be coercively enforced. They can be enforced through boycott, but even if they aren’t, the parties to the contract can still engage in them.
I have to admit that I am not exactly sure how to answer this. I don’t really think it necessarily follows from Lockean rights to property that non use constitutes abandonment law. I think that is a creation that does not need enforcement or can simply arise from people refusing to help you take it back or what not. I consider the object MINE until such time that I renounce any intention to keep it for future use. I think renting it might be a sign that we are indeed keeping it for some reason and not abandoning it. Is the problem then for them that I am keeping it solely to charge others for its use?
Any thoughts would be more than appreciated. thank you.
