Why is P2PKH used instead of the simpler P2PK?

The original reason why addresses were a public key hashes is something you'll need to ask Satoshi. My guess however is that it was just shorter and more convenient (note that compressed public keys weren't known at the time). .. One often repeated argument in favor is quantum resistance.
Our guess is that he knew that the early mined coins will be moved one day. So he created a 'prize competition'. Otherwise he could move the coins to quantum resistant P2PKH addresses, but he did not and is not doing.
The only question is:
Who will win the race and get the early coins?
Quantum computing or solving the "Satoshi Prize Competition".
Nobody can stop that race.
