Exactly. Therefore, if someone else then Satoshi is able to move Satoshi's early mined coins, so Satoshi has to react.
If anyone is going to prevent someone from stealing Satoshi's vulnerable P2PK coins, then it should be Satoshi and only Satoshi. We should not get to decide to deprive Satoshi of all their coins.
You see in bitcoin the majority has been making this kind of decisions for a very long time and it won't be any different for ECC in the far away future either.
Correct me if I'm wrong, but I'm not aware of any coins being made unspendable by the removal of OP_CAT or by BIP 147. This is in stark contrast to the millions of coins owned by potentially hundreds of thousands of people which would be made unspendable by depreciating ECC.
