It’s true that governments shouldn’t require ID to be linked to phone numbers, but in much of the world (likely most of the world’s population), they do.
If we stop caring as soon as enough governments grab more power they'll just keep doing it. We don't have to overthrow the government for something as simple as ID requirements for a SIM card, we just need to stop using them when we don't accept the premise.
Granted that can be harder in some countries that, for example, use phones to pay for everything and don't use cash. That's just another example where people could have refused though, we can still survive without it even if life becomes less convenient.
