You are 10 years too late. Remember when Google plus was arguing that you had to use your "real name", endless arguments about that, very few for why this was a good thing. There were some naive claims that it would lead to some mysterious social pressure for people to behave if their real name was used.
In today's world, the ever more ubiquitous tracking should give everyone pause. Using tor, different email addresses and separate identifies for social accounts should be ordinary. Do you want to have any privacy? Then you need to do that. I don't hold any hope for the legislative bodies to succeed in blocking this. Not at the US federal level at least - there may be hope for California.
