Earlier quoted context omitted.
In what sane universe is not requiring toilets and showers a solution to housing issues? I'm reasonably sure we can meet housing needs and still maintain basic human dignity.
Not all housing need to go to a 4-person family. In my late teens and early 20s I shared a bathroom and a bedroom and never felt my dignity impinged. At that age it was much more important for it to be cheap than for it to be good. It should not be illegal for such housing to exist.
I think a dormitory or barracks style housing is perfectly acceptable as a solution but putting the burden of supplying bathrooms on private businesses or implicitly requiring people shit in buckets in their one and only room is not.
