There are already many of these things... ther origin is housing, build (3d print) new houses, you can build a 2 bed house that will last a century for 10k, it still won't fix the problem, the junkies dont want good or they would go to food kitchens, they don't want somewhere to sleep because they would go to homeless shelters. There arent enough though so why not invest in that, or even better why aren't they building this place in Montana or new mexico where it is cheap.. this is a stupid plan
