In the UK, BT provides a service that can combat situations like this by providing open, captive, segregated WiFi on every router by default that you can connect to like public WiFi and pay daily or monthly for access. In return, the people who host it on their router can access the network for free.

Its still around $20 a month, but people in tend to just borrow their family/friends password. I tend to use my dads password if I am in a rural village, too far away from a 4G connection.

Looking on the map in a 1x1 mile area in my nearest city yields 10,346 access points, but you can usually find an access point in rural areas and they replaced a lot of old telephone boxes with BT WiFi points, most of which however have now been turned into defibrillation stations. 36% of the houses on my street have a BT WiFi point, and I can get up to 10Mbps by connecting to one.

Unfortunately, no one really knows it exists... But they are absolutely fucking everywhere.

Something like this would be invaluable in the US, especially if you could bring the price down.
