That should have read "X points", not "X pixels".
Irrelevant. It doesn't matter where its handled, a finger is fat and imprecise while a mouse cursor is typically very finely positioned.
It is anything BUT irrelevant. It is the essence of the matter.
In case you hadn't noticed, decent modern cell phones are very consistent about where that "point" is, in relation to where you put your finger.
This is not a problem with the UI: the only problem is you getting used to it. It is as precise as a desktop with a mouse, given how finely you can move your finger. Any difficulty there (again, with a decent modern phone) is YOURS, not theirs.
Open up your favorite word processor. Type in some characters. Hit the zoom button. You notice how the font size physically changes on the screen but the point size is the same? Yeah. That.
You are on an old system, aren't you?

But lets assume Apple has implemented perfect font scaling so that when you set your system font to 8pt is exactly 1/9" on both the phone and the desktop. So that same font is taking around 2% of your (vertical) lines on a 5.5" phone while only taking ~0.46% of your 24" monitor.
Straw-man argument. Your original argument was that 8pt was "too small" on some devices (proven false). Now you move the goalposts to some other personal bitch that you have.
Which ends up amounting to the pretty much the exact same problem just coming at it from the other direction -- you have to adjust to fit more information on the larger screen at the same font size (in points) rather than having to fit less on the smaller screen with a larger font size (in pixels.)
Nope. Nothing of the sort. It just means you don't know how to use your equipment. Pardon me if I am not particularly sympathetic.
The primary issue is that a mouse pointer is small and fairly accurate while a finger is relatively fat and imprecise.
I would dispute that. On both desktop and touch screens the pointer position is handled by hardware + firmware, not the app. Also, Apple has already done a good job of managing to scale controls on different display sizes in a way that works appropriately (e.g., on a 24" 1080p or a 27" 'retina' 5K monitor you get controls about the same size). Further, if you hadn't noticed, iPhones now sport screens with much higher resolutions than desktop screens from just a few years ago. These "retina" screens, again, handle automatic interface scaling quite well, versus the older iPhones with lower pixel count... controls are about the same size.
Also, mice pretty much universally have at least 2 buttons that you can take advantage of (and often 3 or more plus a scroll wheel) whereas a finger is just a finger.
That much is true.
An 8pt font on a 25" monitor is barely legible. An 8pt font on a 5.5" phone screen is a dot.
No, that's not true. A point is a fixed unit of size on paper or screen, and has to be compensated for with different screen resolutions. A U.S. point is 1/72 inch and in UK it's 0.3528 mm. An 8 point font on a desktop and on a phone screen -- no matter the pixel resolution of either -- should be 1/9 inch.
If you can't get your work done in the first 24 hours, work nights.
