Technically true, but he's looking for $4 b-b-billion.
Some thoughts about this that interest me:
- Things like the Bitcoin Cash fork & DAO fork arguably set the precedent that the developers control the funds. They never should have done that because now anybody can argue "you did it for them, why not me?" And this time it's being argued in the legal domain instead of just on heated GitHub comments. Judges aren't known for understanding the details of blockchains and can probably swing either way on this, especially if you jurisdiction shop.
- The "assets you don't own" part. He can't prove he had the keys, or lost the keys. But he just needs to present a compelling argument, not have an argument beyond a shadow of a doubt. The fact that the real Satoshi is unlikely to appear to defend themself makes it easier for Wright to argue Wright had the keys at some point, even if he wasn't the first or last owner.
- Combining these points: If you have established you will change the blockchain through a compelling argument; and if _nobody_ presents the keys; but if you have the best compelling argument _without_ the keys, then the coins probably belong to you.
- The big problems that lead to this situation were opening the Pandora's box of blockchain forks; & the tying of physical identities to wallets through KYC (which was the death of BTC.)
