Forget about the politicians for a bit. There still are many regions on the globe where no age verification is mandatory, yet websites chose to implement it anyway. Why, if not for tracking and bots?

Well, because of things like COPPA I imagine most companies wouldn't want to risk anything here. So unless you have a website that is somehow guaranteed 100% blocking all traffic from the US or American citizens, you may as well implement it. But very few (if any) public websites will fall into that category.
