Having just read up on it, sure. But that is a very restricted use case as you could only use your wallet for a single send transaction and that has already happened for the specific case of Satoshi's wallet.

I believe you could scaffold up a system even with a 1-send limit that transparently functions the same as what currently exists since you can issue transactions to multiple parties within a single send, but that largely kills Bitcoin as normally used. All but the most sophisticated users would be required to hand over control of their wallet to actually manage the massive proliferation of addresses needed to act as if you have more than a 1-send limit. But sure, you are technically correct that there exists a very narrow use case which you can probably hijack aggressively enough to salvage the system if you tried hard enough.

You're right that Satoshi's coins are at risk (but because they're using the older P2PK, not due to key reuse), and I agree that this would lead to some amount of chaos and transformative disruption.

BIP32 solved this in 2012, and is used by basically all self-custodial wallets these days. https://github.com/bitcoin/bips/blob/master/bip-0032.mediawi...

Ah, I did not previously know that there were a plural number of Satoshi wallets. I previously read that Hal Finney was the first recipient of a Bitcoin and which came from Satoshi Nakamoto and assumed that there was just a single Satoshi wallet which would mean there is key reuse.
