To me you and others' prevailing argument is similar to "well I don't want to go out of my way to setup HTTPS, I shouldn't need to pay a damn CA to host a blog", letsencrypt solved that and people were still saying they shouldn't have to do that, except the risks here are much more dire, impacting an entire generation of humans in severe ways.
In a way, the internet is a victim of its own success. Finally, it can be used to do just about anything you did in person, including work and learn remotely. But also a whole lot of other things. I was commenting in a sibling comment thread earlier how watching a striper at a strip-club, and watching that same stripper on a free live-cam porn site on a screen are the same bi-lateral sexual activity that society has decided should be between consenting adults. You don't have to prove your ID when you visit a random store, just like with a random site, but a porn site requiring your ID is the same as a strip club requiring your ID. I don't like it same as you, but at the same time, logically I can't argue against the same laws and norms of a country being enforced consistently. We live in a world with terrible people, and so long as ID requirements for IRL are the same as online, it makes sense. it makes a whole lot more sense than expecting social media companies to actually reliably police all content in real time, and if I can have a simple, secure and privacy preserving way of doing it, I'd prefer that over showing my face, my ID,etc.. to random third parties.
