They do exist! There are, I believe, currently a few hundred in the US. They're just spreading very, very slowly. I imagine the main issue is a combination of lack of public awareness + the difficulty of acquiring land + lack of public policy to accommodate the weird structure.

Ah, interesting. I'm familiar with some of the historical land trusts (Fairhope, Arden), but not the contemporary ones... I really need to learn more.

Are people trying CLTs in Detroit? It seems a natural place to experiment with it.

They do exist. What's stopping them from being more prevalent? Probably the lingering effects of McCarthyism.

I think this is a big part of it. I've been jabbering about collectivism for a decade, and almost everyone's first reaction is to tell me why that can't possibly work and there's a reason for capitalism, and if it made sense a company would do it, yada yada yada.
