You're mixing up two different things.
You can have all those fancy graphics right now if you want them on a Quest2 or Vibe or whatever at almost 4k something resolution depending on how you measure it. You just hook it up to a PC and play a VR compatible game on Steam, then you get the power of whatever PC GPU you have. You are looking at the games that run standalone on the Quest2, they are stuck with a massively underclocked mobile GPU to make sure your head doesn't melt.
Not all games are about graphics, and I find the most fun and replayable ones certainly aren't. That's where the standalone headset games have their place... The killer feature of these and the Quest2 in particular is that you just throw the headset on and pick up the controllers, it's like the gameboy of VR, no need to hook up external sensors, a gaming rig and a tether, instead you can stick it in your bag and use it almost anywhere.
It depends what you want out of gaming, I haven't owned a console or "gaming PC" in 20 years, I was never a fan of the "wii" type games, I'm an old skool Doom and Quake guy, so I wasn't convinced about VR until I tried it, and yet now i'm one of those weirdos playing beat saber on expert. I don't care much for modern AAA graphics so their absence doesn't really bother me, I grew up seeing the incremental improvements and it's just more of the same to me, most AAA games all appear to be a small variation on the same mechanic, nothing much changes there. What interests me is novel game mechanics with replay value, graphics just need to be acceptable for that. I'm not after a "visual experience", that gets old real quick. But it's all subjective... just don't knock it until you give it a proper try.
