Why can’t a country just restrict a website/app?

The ongoing absurdity between Brazil and X (Twitter) made me wonder, can’t Brazil just block X domains? Why is it dependent on X doing it from their end?

Fundamentally Internet is similar in many ways to simple mail. Your browser looks up the company address on yellow pages (DNS lookup), then packs a request into an envelope with that address, and sends it. After a while response comes back with some content.

Now imagine a country says “no more sending physical mail to Elon Musk!

Sure, you can ban sending to his home address. But what about his work address? After that is banned too, he can open a PO box. Or a new office. Or ask a friend to receive his mail for him.

You can force yellow pages to remove any mention of Elon Musk. But there’s other Yellow Pages, and also ones issued by independent company from UK, and 50 others.

The only way to *truly* enforce a ban – is to ask Musk himself to comply and not read any mail coming from a CA address. But even then, the sender can just send their mail through a friend located in NY (VPN).
