> I wish municipality offered domains, for example: you move to St Louis you would get name.stlouis.mo.us this would give you the same agency online that a mail address gets you offline.

While a US municipality may or may not operate their locality-based domain (here, the university does), ordinary persons are able to get subdomains under them. The only reason I haven't is because the university here doesn't bother to respond when I follow the process. But you may have better luck where you are.
