Maybe this causes fragmentation of large platforms, that'd also be a net good imo.
Society certainly didn't anticipate a lot of the drawbacks of anonymous presence.
The town square metaphor is really not a great one for the internet. You don't run nearly as high a risk of getting doxxed or swatted for speaking your mind in a physical public place.
And if the unspoken suggestion is that anonymous doxxing would be impossible or too costly/risky in a hypothetical de-anonymized world, I'd call BS. Even if it worked, that would require some kind of "panopticon internet". Sounds bad...
You either need the right to be forgotten, or the right to be anonymous.
Historically, it wasn't current-moment anonymization that was good, but ephemerality.
Sadly, I think the right/ability-to-record is a genie that can't be put back in the bottle (no one can scrape anything?), so we may need to switch from identifiable-but-emphemral (historical state) to anonymous-but-recordable (future state) to preserve the same freedoms.
IMHO, we'd be better off working to curb the worst consequences of broad anonymity (e.g. astroturfing / artificial amplification).
I think Internet anonymity has some benefits though: it's certainly helpful for whistleblowers revealing crimes committed by a company, government or other organization. While you could in theory still drop folders containing documents or a USB drive to different news organizations, with how widespread CCTVs are, so I think that path may become more difficult. In countries with oppressive regimes, that's even less of an option.
I'm also not sure that the lack of anonymity is a sure-fire way to improve public discourse: just look at Facebook comments (which are rarely anonymous.)
As you mention, perhaps anonymity could be allowed on the Internet, but not on the big 5 platforms — that could be a balancing act between chaos and oppression.
Though, while a policy like that might be a net good for someplace like the EU, the precedent of requiring government IDs for Facebook etc. could set a dangerous precedent for places that are less free. Not every country is a full-on liberal democracy OR an authoritarian state where Facebook etc. is outright banned — there are places in-between, where the government oppresses people but still has elections and some degree of dissent is permitted. It's in those places that I see government IDs being required to post on major platforms being a major issue. Being able to share instances of government oppression on major platforms is crucial for those places, but if the identity of those sharing it is revealed, then fewer people may speak up and share such instances.
It's a complex issue to say the least.

Wouldn't whatever "signal amplification" downsides happen just as much with decentralized services
This isn’t a case of “oops we didn’t know the age”, this is about accounts that had an underage DOB set.
