"Custodial = banking" misses the mark. No KYC, no permission, no identity - that's not Chase, that's a bridge. Phoenix: 12 words, your node. They vanish? Force-close, timelock, recover. Non-custodial with training wheels. And your "pure" sovereignty? You're still trusting ISPs, cables, maybe their bank. You fabbing hardware wallets? Running a full node from your pocket? Sovereignty is a stack. Purity tests are cosplay. Build ramps, not walls. Pura Vida.
