So, what real reason is there to buy a PS6 now?

I know it's a bit of a tired topic, but I'm trying to be realistic here. What reason is there to buy a PS6 now that they're going digital only? If I wanted digital only, I could just go to Steam. What does PlayStation offer that Steam doesn't? Their exclusives that seem to flop at every turn and stir up controversy with each release?

Realistically, what is there? Devil's advocate?
