I say it's a business opportunity, why don't Americans just open a small general store in their residential areas? Not everything need to come from a supermarket, here we have people that literally sell you vegetables in a rented garage.
Seems like the only acceptable usage of garages for you people are tech startups and maybe teenager bands lol.
I hope the answer is not "due to some obtuse regulation, residential areas can't have business operating in any shape or form, unless is a tech startup or an ice cream truck".
I think I understand now why another commenter said that they are not obtuse laws. Obtuse laws emerge organically from idiot people, this is very malevolent and intentional. These fuckers have been around more than 100 years fucking up your community planning.
edit: wow, also racism is involved in this? I mean, I shouldn't be surprised, but still...
