I know I'm in the crazy minority but I'm over anonymity at this point. I want to know who's a real person and sincerely who they claim to be. The harms of trolling, scamming and societal mis/disinformation, for me, outweigh whatever benefit exists in anonymity. I've never assumed I was anonymous from the government anyway so really, we're just anonymous from one-another. Seems like a classic method of divide and conquer now that I think about it. All that said, I have no idea how to safely enforce ID'ing without some kind of authority (goverment or ideally something else).

You investigate and punish groups found to be running psyops, simple as. No need to automate the whole process with ID checks, these organizations make and spend money so the tracks are there to find. If suspected drag them into discovery and gather evidence like you would for financial fraud or criminal conspiracy.
