And this is so problematic. First of all, there’s really a chilling effect going on with putting your real identity to your online posts. I’m not sure if I would be posting on here if everybody could link my profile here to my real name. There is a reason why people are not discussing depression, drug use, or marital problems with their work colleagues or neighbors. And people really would not like if prospective employers could see everything they are writing online.

I think that the big problem is that more than putting your real identity to your post there should be a way to identify you in case it is needed, anonymity cannot be a free pass to commit any kind of crime.
Online you are not really anonymous anyway, your provider know where and when you go to a site, it would not be difficult to trace back to you if someone is willing to do it.

I don’t know how this problem could be solved btw.

There’s also a chilling effect on political debate. You really do not want your home address being available to violent Neo-Nazis, Hamas supporters, Covid-deniers and other idiots. That will lead to harassment and this will lead to people stopping discussing certain topics.

Well, if anonymity is removed also the violent Neo-Nazis (or whatever) is exposed, maybe he would think twice before doing/saying something stupid knowing that nothing stop someone else to make him the victim of harassment or to be treated like an idiot or ignored at work (or any other real life situation) because people find his social accounts and simply decide to not interact with (if not totally boycott) him.
Yes, maybe not the first time, but in the end people like these will return where they belong, in their small circle of idiots.
