Thinking about it, it does surprise me that America never adopted long wave as LW signals travel even further than MW.

The US also prizes localism, possibly once again due to its immense geographic spread and relatively sparse population in most places. An AM transmitter in the principal town in any given locality would serve that town and also any outlying communities that considered themselves its satellites. There would be no need to try to reach the next principal town as they would have their own (and if one of the many standard tropes of American popular culture is to be believed, every small American town loathes its near neighbours anyway, so wouldn’t be interested in listening to their radio stations).
