Not all people without an address are "incapable of functioning minimally in society", even ignoring the profoundly undemocratic implications of what you're say

Not all people without an address are "incapable of functioning minimally in society", even ignoring the profoundly undemocratic implications of what you're saying. When I was working as an archaeologist, I often lacked a residential address. I had a stable job, supported local communities, and generally met residency requirements, but establishing that in the normal ways was impossible. I've also had at least one ballot rejected as a result of similar clerical issues. It's often helpful to be a bit more open-minded about how different other people's lives can be to your own.
