Projectors don't even have surface area! There's no fixed projection distance.

  Projectors are supposed to allow you to disrespect that. You don't use a projector the same way you use a tablet or a desktop monitor. Monitors are not. They have fixed surface area and it's entirely possible to respect that, since modern monitors identify themselves to the OS, so it's relatively trivial to calculate pixel density. This sizing system was designed to be used with paper and PostScript printers respect it (or it'd be impractical to drive printers with different pixel densities).

    Tell me again what happens when you drag a window across monitors?

      I have monitors with different DPIs. Text is about the same size on each, because I setup scaling correctly. The OS resizes the app according to the monitor that contains 51% of the window. Janky during moves, but if you keep the window on a single monitor, it works well. (I always liked Chrome OS's solution to this problem: you can't span windows across displays!)
