Sure, but nobody is using 8pt CJK fonts. Even with a 5k panel, you wouldn't be able to resolve their shape without the equivalent of a magnifying glass (i.e. focusing on a smaller section of the screen). Talk about eye tiring.
*px but yes, precisely my point (wouldn't be so sure about "nobody", though...). On higher resolutions, more pixels in the same physical size. I find 10~12 all good, depending on circumstances.
But physical size is exactly what matters wrt. resolving a shape. Already at 1080p, the pixels are too small to resolve individually when comfortably looking at the screen. So there's really nonbenefit to such tiny character sizes.

No, and people perpetuating this myth is what annoys me - that physical size is comfortable for me and that's what I use on a daily basis.
Try 8px font of full-width Chinese characters on 14" 1080p next to the same effective physical size on a 4k and if you still tell me it's too tiny to tell, well, I guess we have different eyesight and preferences.
