The real danger isn't the ban itself... it's the precedent that could be built on top of it if governments decide they like controlling digital participation
Texas SB2420 requires age verification to download apps.

Government-endorsed technofeudalism with inverted totalitarian features normalizing deviancy to become shameless, traditional totalitarianism.
-> Scenario
Want to use cash for lunch or parking? Sorry, no, you must be banked, and have an app.
Want to use a bank? You must use an app.
How do you get an app? You must have a phone and an ID.
Want to buy a phone? Whoops, conundrum encountered.
(And don't even think of wanting to get an ID.)
