Consoles are not an open platform and they must force authentication schemes in order to enforce device bans and firmware security updates. Sony will not allow 3rd party authentication to their device network stack as doing so will result in a completely unmanageable security threat to their platform.
I would also like to state again that on my ps3 I could play the game without being signed into psn. So again yes it is possible to remove the sign in for ps4.
