Another issue in my locale would simply be the availability of land. Pretty much every empty lot was snapped up during the real estate bubble. My house is small by contemporary standards, but not tiny in any credible sense.

But it's worth noting that by "tiny homes," we mean specifically tiny detached homes. Within a few blocks of my house are some four-banger apartment buildings with ~ 1000 square foot units, and I could probably afford to buy one and rent out three of the apartments. That could actually be a realistic option if I ever become an empty-nester.

I've seen a few implementations of that. There are obviously the micro-condos in NYC, but tiny house villages have been cropping up (like trailer parks, with less of the stigma). More land-efficient are the shipping containers as condos are becoming more popular too.

They are exactly that, yuppy trailer parks
