Because the USA incorporated 'America' into its name before anyone else did? Because the US Naval Academy has already claimed USNA? Because custom tends to outweigh pedantry?
In fact, did ANYBODY else use 'America' in their name?
Really, the USA is not so much a name as a description. Its maybe the only country on two continents that fits that description. So its a really good name.
