Aren't these all issues with the current system also?

I mean if someone has two addresses which one do you deliver to? Right now they manually decide, in this "system" they would just set up their default person routing to either one.

Homeless people would likely get a code, but realistically delivering to them might be difficult with no fixed address. But that is also true today. In both systems they could get a PO Box.

I guess, it won't solve either scenario any better than the current system, but it doesn't make the situation worse either...

As for businesses, there's no reason a business entity couldn't get a code and set the routing however they wished. Just treat them like "individuals."
