It’s because the hard “problem” isn’t the shelter piece. The hard problem is how do you house a lot of mentally unstable people who can often be a danger to themselves and others at the same density as the rest of the city and at an affordable cost. I don’t think it’s generally possible because as soon as you hit any kind of density with these you get problems, but you need a minimum density to provide bathrooms showers and services. The best solution that I’ve seen is forcing builders to incorporate 1-2 subsidized units into every new building, as that distributes the problem around in a manageable way. Still that likely will not yield a quick solution and may never hit the required number of units.
