That's not really a fair assessment of the Quest 2. The Quest 2 is just a budget (400 Euros) gaming console, and for that it works great.
A 400 dollar gaming console with a theoretical resolution of 1,832 × 1,920 per eye, is obviously not gonna perform well if you use it to emulate high resolution virtual monitors meant to sit further away from your eyes, further decreasing the perceived resolution, so you can read text and perform productivity tasks. Of course it will suck at that, but it was never meant to do that.
That's like complaining your Toyota Aygo sucks at offroading or track racing.
