There is no need for it. Sorry. Certainly not government mandated, which is the worst part.
YOU have no need of it. You're projecting your experiences onto everyone else. Maybe you're content only hanging out in limited forums where you have to know someone to join. And those forums can continue to operate without any human verification. If you don't care whether the spaces you occupy are infested with bots, or can manage with white lists, fine. But most people don't want to talk to bots. Not everyone has the social connections you do.
I don't support mandating ID for anything. But you are not the only person in the world. Just because you have no need of it, doesn't mean no one does. Not everyone uses the internet the same way you do.
"Only join forums where you personally know the people there" is not a scalable solution to this problem.
Respect a diversity of viewpoints and experiences. Your way is not the only way.
