Is the American government weak enough? Could we just apply these principles locally?

We need many rich supporters to buy land in a place with a weak government.

This happened once before, and it actually worked! A bunch of people took some rich investor's money to set up shop on new land. However, once their society was flourishing, the investors wanted to tax the shit out of these people until they couldn't take it anymore, they revolted, killed their old master's army in battle, and then set up a charter blocking all bankers and tyranny for almost 150 years.

I think it was called... America? Something like that anyway.

Seriously though, what's to stop a likeminded group from doing the same in Alaska or another part of the US?
