Go back to the 80s and 90s even. Remember how only really poor people lived on Capitol Hill and how it was the place you went to score heroin or a hooker? Man, I miss that culture. Sorry you gentrified it only to have college kids move in. Sucks.

But joking aside, I do think that micro apartments speed up the population growth faster than is sustainable. Your small businesses give way to chain stores, and there would be lines everywhere if you didn't crack down on microhousing -- unless you were also able to introduce some sort of "microhousing-equivilent shops and services" model. (Maybe crowd-sourced delivery would partially work, but there's something to be said for having a local coffee shop with a free table.)

In the early 2000's we crammed 4 people into a 3 bedroom apartment near The Harvard Exit. Our total rent... $1600 a month -- I think my cut was $375 -- and another $25 / month parking. So in that sense, I don't think microhousing is any worse than what we did, but there certainly weren't that many people lining up to live in Capitol Hill back then...

To this day that was my favorite place to live.
