These do help though. They’re great for student housing for example. Here in Albuquerque there is a long tradition of casitas that is thankfully being expanded through relaxed zoning. It provides a relatively quick way to increase density in areas built up with SFH without facing much nimby pushback. Housing prices are detached from supply/demand somewhat but not entirely, increase supply enough and prices drop.
Except you don’t need to eat animals and so it is the same. You’re killing animals for your entertainment, just because you eat them after that doesn’t change anything.
