Know why? Because we don't fucking have to. We can literally do whatever the fuck we want without conforming to the rest of the world's standards and suffer few to no repercussions. We have sports teams in our own country that are more relevant and prosperous than most of your leagues. You faggots will literally convert things to OUR measurements to please us, despite our units being the exception.

Name a more relevant country than America?
Pro-tip: You can't.
