Sad thing is that is is USA that is the problem child in all this. Being largely isolated from Eurasia, and having just a few big neighbors that are easy to convince to play along, they can basically define the spectrum within their broadcast reach as they see fit.
It is basically the same reasoning behind it as why metric is still not the default over there.
Well, and that works in our situation.

There's also the simple fact that the 'metric' system is just different, not superior in general (i.e., it's better at some things and worse in others). Why impose a bunch of costs for no net benefit? If every other country jumped off a bridge, ought we?
Three, I'll give you.
Useful amounts of precision is a nothing, if you ask me. We start teaching decimals in third grade, and the only real issue with decimals is weather, for which the difference is saying "80F vs 81F", or "26.7 versus 27.2", whose utility is ... limited.
For distance, the metric system has finer grained units for precision (come on, break down inches: 1/16, 1/8, 3/16, 1/4, 5/16, 3/8, 1/2, etc... are you going to argue that is better than 25.7cm or 257mm?).
I'm not really buying it, as someone who has lived in both worlds.
You can say 1.5 cups instead of 375 mL.
Just like who hexadecimal is very natural in 8/16/32/64 bit computing, the "real life" usage of measures would be much easier if it was in Base-12.
