      WiFi already manages this. Systems set up like eduroam have a student sign in to their university WiFi one time and have access to WiFi across their campus and all other universities that support eduroam.

      There are also commercial options. ISPs offer a similar service where you enable your home router to broadcast a ISP connection point alongside your normal WiFi access point. This enables you to join any other ISP connection point where ever you go.

      The issue with this is control. You would have to give up control of your access point to the centralised system. So your internet access may be limited by other people using your line.

      Don’t some ISPs (like Xfinity) already do this by making a second WiFi network so that anyone with their service can just roam between routers?

      There is, it’s called WPA2-Enterprise with 802.1x and RADIUS.

      But it hasn’t really been implemented for the “everybody” users because you generally don’t want random people on your network. If you want to participate in a wide-area roaming network, you can use the cell network, because that’s run by a single entity you can establish a legal and financial relationship with.
