> 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.
