> Wouldn't these points also apply to the internet itself? Large monopolies in infrastructure, having to teach people what domains are, diplomatic conflicts between nations over access to information/infrastructure, prolific spam and scams, etc.

Yes, many similar problems have indeed arisen, but the point is that they are being solved by many private actors, and not by regulation.

Email spam is solved by spam filtering. To the extent that spam filtering isn’t adequate, communications simply move away from email to other messaging services that have better permission models. To the extent that messaging services are not private enough, communications shift to E2E encryption. To the extent that domains are confusing, people shift to search and apps. The list goes on.

Phone spam however, continues unabated.

Spam is not solely solved by technology, regulation also helps. Regulation also helps with phone and text spam, though there's more to do.

Anti-spam legislation doesn’t regulate the technology. It legislates the behavior of the spammers.

This is no different from say, assault, which doesn’t regulate hammers and baseball bats, but makes it illegal to hit people with them without their permission.

Your comment seemed to be claiming that, at least in the example of email spam, only technology (filtering) addresses it, that there is no role for regulation. I was disagreeing with that.

My understanding of phone spam regulation is there is some that legislates technology, namely forbidding completion of connections of spoofed phone numbers.
