Objectively, higher frame rates are 'better' in every way, and objective tests can demonstrate it: people can complete interactive tasks better at higher frame rates; in gaming they can judge time to impact better, etc.
I'm not expecting McDonald's to get bankrupt any time soon due to food quality problems. Or the mp3 industry. Or the YouTube videos. Or... Try to promote the FLAC format to teenagers and see what feedback you'll get (on average, of course).
The fine line is where the industry starts promoting junk*) as the best thing since sliced bread, for pure commercial purposes and using the junk*) as product differentiator. Myself, I have no problem with people living with their favorite junk*) until they try pushing it down my throat.
