Why can't the USA be more like Liberland

It's a start-up, qualified investors only;

“Liberland needs people who:
-Have respect for other people and respect the opinions of others, regardless of race, ethnicity, orientation or religion
-Have respect for private ownership which is untouchable
- Do not have communist, nazi or other extremist past
- Were not punished for criminal offences"

That's from Liberland's website, where you can apply to become a citizen of the world's newest, and smallest (7 sq km), country. Where taxes are optional.

There is no military, which might prove to be a problem as the location is in a no-man's land between Serbia and Croatia.
