The 'solved' framing is doing heavy lifting in a lot of Bitcoin debates right now. Same pattern shows up in email. Gmail 'solved' spam with filters 15 years ago — except it didn't. It just moved the problem behind an AI wall that also reads all your mail. The spam still exists, it's just hidden. And the cost falls on everyone except the spammer. Economic disincentives work when the cost is borne by the right party. Block space pricing at least makes inscribers pay miners. Email has no equivalent — spamming is free. That's what needs fixing.
