If the United States of America was renamed, what should it be?

To my knowledge (that is, a couple YouTube videos on the topic, this could be outdated/false information), there are some people who aren't happy that the U.S. names itself after the continent of America (implying that they have a right to all of America, manifest destiny to the max). Whether that is true or not, naming stuff is always fun, so what is a good name that is representative of what the U.S. is?

My personal suggestions:

• The Liberty States
• since Argentina is the only country named after an element (silver), why not another? Perhaps the U.S. could be named after gold, after the Gold Rush which I think was a big thing? That or an element that can be red, white, and blue. Speaking of...
• The Republic of Red, White, and Blue

Please assume that stale carrot man isn't in office and that the U.S. is currently being a reasonable and humane country that actually stands for democracy, liberty, and freedom.
