We've torn down about a million SROs in recent decades and zoned out of existence a lot of housing options that are being termed Missing Middle Housing.
The current YIMBY movement and Missing Middle Advocacy is the latest attempt to try to address this issue. New Urbanism was a previous one.
None of them get at the roots of the problem, which date to "the boys" returning home from WW2 and the birth of the modern American suburb.
In a nutshell, the vast majority of our housing financing mechanisms, tax incentives, etc etc are aimed at helping people get single family detached homes and homes today are more than twice the size they were in the 1950s while housing about one less person.
So our housing policies have caused "home inflation" in some sense. Homes are bigger and have more amenities -- or don't exist at all.
We now expect single people to rent a place designed for a nuclear family and get roommates to fill the empty bedrooms and split the rent. Then we make movies, like Single White Female, about what a nightmare it is to be forced to make ends meet by living with a total stranger and do nothing to change our policies.
I've made several stabs at trying to write about this, but none of that has gotten any traction.
Here's a few things by me:

You are right that posting on the internet is mostly a waste of time. But I'm medically handicapped, so it's where I spend the majority of my time, though I would prefer to actually have a life. I simply don't.
I am involved in stuff locally in my small town. I'm no one important and it may never lead to better housing here. On the upside, the local police department does hand out my fliers for homeless resources -- which is mostly websites, mostly written by me. So maybe the time I spend online isn't a total waste.
Have a great day.
Edit: Those are not intended to be "substantive" supporting links. I've studied this problem space for decades. I wanted to be an urban planner before life got in the way. I don't know of any other sources that will say exactly what I would like them to say. Sorry.
