If you still believe in the core concept of a state, but just believe the US is a particularly bad one, invest in other governments with opposing, or non-aligned geopolitical / economic interests. Iran, Russia, Brazil, India, China (and/or corporate entities therein) are good places to start.

If you believe the entire model is intrinsically flawed and doomed to eventual failure, cryptocurrencies if you're technologically optimistic, or precious metals if you're not.
