Hold on, the last time you didn't have to log in to use a PS console was... what, 2005? And you are seriously claiming in public with a straight face that you don't use any gaming services that need a log in on PC? So... you use none of them? Not Steam, not Gog, not Epic, not Xbox, not EA Play or whatever Origin is called... none of those.
Well, I mean, bully for you, but I'm gonna guess that Meta is after a different demographic than... you know, people who don't buy videogames on their videogame systems. Login absolutely has been a requirement for standalone gaming devices for the past twenty years, with no meaningful exceptions.
Specifically, though, what VR device do you use with no login? Because last I checked, all the places that deliver VR software have their own. The Oculus app does. Steam does. PSVR does. Apple sure does.
So... what type of mythical beast are you to be using this rawdog VR device with no login involved? Are you just beaming I Love Lucy to an HMD using the power of imagination?
