If housing isn’t an economy at all, I can understand how you came to that viewpoint in your original comment. But, I feel that as a usual internet comment, it was exaggerrating and envisioning an ideal world.

We aren’t living in one of those. When I read that comment I understood it as basic housing not being an economy, and luxury housing still being purchasable-- which is much more realistic. And so I wanted to give a bunch of examples in the ways that it is feasible to create basic housing even in our capitalist system today.

I mean, hopefully in the future we can get to a post-scarcity economy where not only is the housing provided for free but it is also exactly what we want. That day won’t be for a long time, though…
