ISPs as publically owned Utilities

Hey everyone, I'm new here but all this news about age verification and data privacy got me thinking about how the Internet itself works and how we connect.

I recall hearing somewhere that a town in the US created a city run internet provider and it significantly increased speeds and lowered overhead, as well as provided more of a voice to its users.

How would you go about implementing this from the technical side? I figure it would be an uphill battle politically, but I don't see a lot of good alternatives in this day and age. I love the idea of I2P and Yggdrasil, but as a matter of user accessibility, they take at least some technical experience and time to set up.
