P2PKH why the hash and not the address itself In a pay-to-public-key-hash script, what is the reason of storing the hash of the address and not the address itself, since anybody can copy the hash from a previous tx resolved by the same hash (i.e. Security is not one of the reasons)?

Is it maybe just to encumber the identity of the payer if he wants to show the hash of his address rather than his address?
You can also do Pay-to-Public-Key.

But public keys are bigger in size that public key's hash. Thus, Pay-to-Public-Key-Hash was invented by  Satoshi to make bicoin addresses shorter.

Compressed public key - 33 bytes

Public key hash - 20 bytes
