If you mean citizenship as being associated to the city whose hosting services you are using, yhe power or water bill pointed at your name and residence should be able to do that. Now, if you want that plus anonimity, the only practical option I can think of for a city-wide physical campaign is some sort of GPG Signature Meetup (“signature party”).
yhe power or water bill pointed at your name and residence
Many people live in cities without owning their house. So they never see those bills. Renters are usually two levels away from the actual owner. Then there are all the people who live and work in cities but aren’t official renters.
That quickly becomes a tragedy of the commons. The city residents pay for it but how do you verify “citizenship”?
If every city has the same then why would you even want to?
