For a simple web app, yeah, I'd agree that trying to get over 30 fps is pointless, especially on mobile where I'll be concerned about battery usage.

But for gaming, anybody that can't tell the difference between 30 fps and 60 fps is blind. I have a 144 hz monitor, and I can certainly tell the difference even between 60 fps and 144 fps.

The UFO Test [0], while contrived, will show you the difference. If you have a 60 hz monitor, it will show things moving at 60 fps and 30 fps (And 15 and 7.5 fps, if you want). If you have a 144 hz monitor, it will show 144 fps, 72 fps, 36 fps, etc. The difference is clear, especially if you're following the UFO with your eyes. The higher framerate is less blurry. In games, this can be huge.

It could be some kind of placebo effect, but I know the difference between 60 and 150+ fps even on 60hz screens. At least I'm sure I can feel it when gaming.

It is 100% placebo because a 60 hz screen can only render 60 fps. If you're getting 150 fps, then if you're playing with V-Sync enabled, only 2 of every 5 frames is being shown to you. The other three are being thrown out, never reaching the monitor. If V-sync is disabled, then you're only seeing about 2/5ths of every frame with a tear in the screen when the next frame was shown, causing rendered objects to shear.
