Unfortunately, in the earlier stages of Bitcoin, P2PK was implemented instead of P2PKH. The earlier transactions, specifically those that were mined to were vulnerable with the default implementation using P2PK.
I don't know why you say that. Even in Satoshi's genesis block, the output script is

that is essentially a bitcoin ADDRESS, meaning, it is a hash of a public key.
