Once you drop stupid arguments that can't work their heads around the distinction between a pedantic argument of locality and just the style the reason why the US doesn't make anime falls into two reasons.
1: Marketing.
More than anything else Americans don't really accept, or rather, no one up top has ever decided that cartoons can be anything beyond children's shows and comedy. At best what you see is a show or movie that hits the audience at a lot of different levels and says a lot of different things to different people. EG: Pixar movies, Avatar: Legend of Korra. But even a show as popular as Avatar only got booked for a single season, and even Pixar is falling into the meta-motions of a creatively tapped studio.
2: The fan base.
Anime's its own worst enemy. Outside of Japan most of the folks who actually watch anime do so over the internet through free streaming sites, and even if everyone went through legal channels it still wouldn't really put food on the proverbial table. Folks really take it for granted that classics like Cowboy Beebop and even the more spectacle driven shows like Evangellion and FLCL were somewhere in between genius and accident. Beebop was supposed to be a kid's show that ended up in airing limbo while the network tried to figure out how the hell they were supposed to pitch it. Evangellion was a censorship nightmare, and it's director had to go on prosac. Not so much in the case of Eva, but for Beebop the only reason it really grew beyond small cult classic is simply because of foreign interest. And you see it elsewhere- Big O and Ghost in the Shell : SAC only lasted as long as they did because of Adult Swim.
