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.
It would have to be a national mandate that is available in every city or everyone would use the free service from one city but not vote to raise the taxes in their city to pay for their own.
If it’s a national mandate, then might as well make it a national service.
