I heartily disagree. All it takes is the one time, for whatever reason, that you have to type in a string of a few dozen random characters by hand on a phone keyboard or something because you're on a new device, or cut and paste is disabled, or whatever, and you'll understand why long random passwords should be reserved for web servers and so on and never used with consumer web applications like a hotel reservation program, or rental car app, or similar.
