We can preserve everything that we currently do. We can use the money amongst ourselves and even create a new exchange system if we want. We already have many people as doctors, policemen, and lawyers to make our own autonomous country or countries.
Just don't feed the snake that bites you. If you realize that you are a slave, why would you continue to pay the rich? Cut them off of your taxes and anything else that we grant them to lie to us again and again. We don't need to fix the system, we need to replace it. 99% of your government is corrupt and we don't have time to go for them one by one. We can make a new country and the honest 1% will come to us.
To do that, we need land and internal ways of communication. They don't want to be around unvaccinated or conspiracy fact-checkers... Then so be it.
We can make our own community exactly how we want it to be made!

Visible assets attract predators, so keep that in mind.
