Another way of looking at it is that tying taxes and other services to the notion of "residency" is outdated. Where I am, we pay income tax based on our province of residence, so if you work out of province (and many do in border areas) you still pay income tax where you claim your residence is. Maybe this should be simplified so that some other factor defines tax jurisdiction... likewise with drivers licensing, why can't I "buy in" to the licensing system of some jurisdiction. Same with healthcare if it's covered.

I certainly imagine there are lots of flaws in my ideas, but it would be nice to see steps away from the assumption that each of us has a long term residence we can get mail at. Just like you used to need to provide a "home telephone", it's becoming less valid of an assumption.

Like you say though, its probably not high enough on many peoples agendas, and is threatening enough to tax revenues (it would mean competition if nothing else) that it's unlikely to happen
