I'm in the same boat. Due to my vision not being perfect even after correction, a Quest 3 is entirely sufficient.
I keep hearing this argument, and it baffles me. I find that, as I age and my vision gets worse, I need progressively finer text rendering. Using same-size displays (27") at the same distance, with text the same physical size on screen, 1440p gives me a much worse reading experience than 4k with 2x scaling.
I'm 53 and the Quest 3 is perfectly good as a monitor replacement.
