The Fitt's Law benefits decrease with the distance you have to travel to reach the bar, though. It always takes me several gestures on mouse or trackpad to reach the top bar on modern display resolutions. Better to just have good accelerator keys (not that any of the major desktops seem to do that in a discoverable way).

First, resolution should have nothing to do with this. Second, even on the largest 4K display that I have, and assuming that you have a mouse curve with acceleration, I only have to thrust the mouse for about 1-2cm of physical distance in order to reach the opposite edge of the screen.
If you are moving the mouse ultra slowly to the edge, then yes, it may take a while to reach it. But the entire point of Fitt's law is that you just thrust the mouse towards that edge as fast as you can since you're not going to overtake it.
Some people do not use acceleration (but one can argue that they are in a minority). I was pro acceleration until I bought a steelseries pad with an aluminum legs mouse. A home tech that never migrated to my workplace so quickly.
Fitt's Law says ease of use is a function of size and travel distance. Items on the edge of the screen have "infinite" size, so they're "infinitely" usable (according to fitts law)
