The idea isn't wrong and there are certainly people who will think twice about anti-social behavior if their real name is attached to it.
The only issue here is that some people think they're entitled to use a pseudonym online on somebody else's platform that doesn't want them to. Ya'll need to go spin up a 5-person Mastodon server to echo-chamber a bit and hopefully learn you're behavior isn't acceptable to most for reasons that go well beyond you thinking you're a victim.
And for the few people who want to use a pseudonym online for reasons beyond anti-social behavior, FB has tools to protect your account notably for journalist. I get you'll have to use someone else's platform for communications at times, but FB has no interest in quelling this and you should just do what you need to do without trying to publicly sway opinion for likely other and hopefully unrelated anti-social reasons. FB is a social network, not the front page of the internet, and they have their own position to uphold that is beyond its users and clearly documented in TOS that people like pretending doesn't exist or cherry-picking to promote victim-hood.
FB and Zuck are not some boogieman out to get people lol, and there's plenty of different platforms to do whatever it is you need to do safely, or not at all.
