Nonsense. You reduce house prices by increasing supply via construction of apartments, and potentially having a land value tax. You don't do it by undermining property rights. This just makes everyone's reality a living hell and doesn't solve anything. What a truly sinister worldview you've adopted.

While I find your proposal agreeable I feel bound to point out that it's not really happening, and meanwhile abusive/exploitative property investment practices are going on day by day. I think in many jurisdictions too much importance is attached to property rights and that is exploited by wealthy individuals and corporate actors to the great detriment of their neighbors and the health of the economy.

Disagree that too much importance is placed on property rights. It's one of the necessary conditions for societal prosperity. History is very clear on that.

Disagree that the wealthy are "exploiting" property rights. The wealthy are exploiting government to push through NIMBY policies that cap supply, similar to how the poor are exploiting government to turn the other cheek and decriminalize squatting.

If you subtly erode property rights by decriminalizing theft you get a hellscape and decay. You haven't helped the poor, you've helped the worst and most shameless moral characters in our society.

My former colleague was a victim of squatting. He owned one apartment and rented to live and some asshole who is apparently a serial squatter moved into his apartment and refused to pay. I will never support the psychopaths doing it and I will never support the ideologues enabling these vampires.

Well, I don't have time to argue with such absolutism.

I'm an absolutist about property rights similar to the way you might be an absolutist about slavery or murder. It doesn't make me wrong.
