If you're not in the US, you probably don't understand how our system of federalism works. We have 50 different states, some of which are basically run by the Christian equivalent of the Taliban or the Shiite mullahs of Iran. These state governments often come up with goofy, performative laws such as age verification that are normally set aside by higher courts as First Amendment violations.

I say "normally" because the same religious factions are rapidly expanding their dominance over those very courts. Absolutely no historical freedoms can be taken for granted in the US right now. Nevertheless, the fact is, there is no national Internet censorship regime including age verification. No such laws are currently under consideration at the national level.

(Yes, you can be prosecuted for downloading or distributing child pornography, but that is not an Internet-specific issue, and there is no other country I'm aware of where such laws are not also on the books.)

Edit: if you are willing to move the goalposts that far, there is probably no way to convince you that the facts are as stated. Nevertheless... those are the facts. For further reading, look up the term "prior restraint." That's what's actually different in the US versus other countries that use technical means to enforce legal restrictions on Internet speech.
