It would also be harder to tune into a station that is SSB because there's no carrier to detect. If you're slightly too high or low, the audio will have a slightly higher or lower pitch. I'm just guessing but with modern radios that wouldn't be a problem, but when AM was still used a lot I think (analog) oscillators tended to drift a bit, and you would have to adjust your radio often to correct for the changing pitch.
