What about businesses that can't afford to own their address?
Then I honestly have to question what sort of business they're even doing. Is this even an actual thing?
The problem here is that there are numerous instances of a bunch of empty shell corporations living under one roof by the hundreds simply for tax purposes and the ability to easily hide assets. They're not
real businesses and exist purely for the purposes of abusing loopholes. A business that doesn't actually have it's own address is hardly a business at that point, and could just as easily exist for tax purposes at the owner's home.
