I've wanted to look more into CLTs, but haven't yet--
What's stopping CLTs from existing today? Is it merely the novelty and relative complication of the CLT? Or is there policy that makes them impractical?
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.
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.
