I always assumed it was a compromise between memory usage, refresh speed, and the GUI that they wanted. Don't forget that the Macintosh was preceded by the Lisa (800x364) and the IIGS (640x200), so they probably had a good sense for what was comfortable given a certain resolution.

Lisa was January 1983

Macintosh was January 1984

Apple IIgs was September 1986

The Lisa was also about twice as expensive as the Macintosh which is why it failed hard. So the price limited the hardware and that caused this display bandwidth constraint.
