People continue claiming the PlayStation portal doesn’t require remote game play and you can log in to your account and access your library, but only Ps5 not PS4 correct?

Now if PlayStation came out with a handheld console that could not only access the library but have physical games… that would be the real deal and sell like hotcakes! I still have PS4 because it works the games are stellar and I love the slim 1TB with a disk drive!
