" Anonymity of users: validating someone's real-life identity sufficiently would make it possible to permanently ban malicious individuals and filter out bots with good effectiveness, but it will destroy anonymity online. In my opinion, literally untenable. "

What about zero knowledge proofs? Those with typical cryptocurrency wallets could leverage existing extensions. Everyone else can download an open source extension that sends the proof and an open source way to verify proofs but is unrelated to cryptocurrency. While a robustly decentralized chain like Bitcoin and Ethereum would be a good place to verify proofs, no reason a non-cryptocurrency solution can't also be avaliable as well for the cryptocurrency adverse. And for the tech adverse, a phone number to call/text to walk the person through sending the proof via phone that would cost a tiny bit--and could also help the tech adverse with setting up an extension going forward?
