DPI is only half of the picture though (forgive the pun). Viewing distance is the other half, your eyes can't tell the difference between 100 DPI and 300 DPI if you're far enough away.

So what, do you read books ten feet away to reduce eye strain?
A modern desk gives you about two feet between you and your monitor, which isn’t overly close, and you’ll still very much notice the difference between 138 and 220 DPI.
Only for my 150" books ;)
I sit 3ft away from my monitors, at that distance I can't notice a difference.
Bingo. And it's less stressful for the eyes to focus on an object that's further away. Net result: I might actually have some vision left over by the time I retire. Worth the cost.

Yeah but we're talking about computer screens, not televisions. The viewing distance is around 20-30 inches and 100DPI definitely does not cut it at that distance.
You're not wrong but at around 30" is where is starts not to matter (for 1440p anyway) and I happen to sit ~36" away from my monitors. See [0].

'Retina' is just one metric. When it comes to crisp edges, there's still a difference up to 5 or 10 times the PPI.
The standard from decades ago is 96. Just wanting to double that, to make the pixels not blatant, is not extravagant.
Ignore the raw resolution here. Talk about DPI.
