I could see ISPs being eventually put in a position where--given concerns of cybersecurity, liability, profitability, and absence net neutrality--access to domains gets treated more or less like cable channels.
You'll have a basic package of a hundred or so approved non-foreign "safety-certified" domains that tend to be part of your phone or Internet bill, and then access to other domains is available if ISP-consortium approved and you pay. There won't be very many because there will be a complex regulatory environment both for domain owners, providers of the service behind the domain, and the ISP allowing access. To register and provide services under a new domain you will have to spend a lot of upfront capital or work under an established regime.

No clue. My crystal ball is dark. I guess UUCP would still work if you can get a dial tone somehow lol. I'm sure we'll still have phone numbers.
