I doubt it would be 100% completely possible, it was more of a hypothetical thought in its self.

Knowing most services are reliant on the internet now, such a POS (point of sale) devices in stores, home phones, condo intercoms, buying airline tickets.

Its would definitely be easier to just stay away or block enshitified parts at the firewall level. Though in some cases even then I find myself using Facebook for its Marketplace only as a example.
