As long as you live in a country, you are bound to obey the law of the land. The government of that particular nation controls the military, the internet, and other areas. There is nothing much that can be done because you can't fight the government that makes, interprets and enforces the law.
The best we can do is to support crypto-friendly politicians and lobby lawmakers to make laws that give the sector more freedom. I also doubt if these measures will be effective because Bitcoin stands for decentralization, while the government is a proponent of centralization.
One can support creation of the new countries!
So... Keeping in mind all the land of the planet has been already divided, you are either calling for insurrection within one'a country or invasion or other countries, which obviously can carry serious consequences, including serious prison time or death penalty, depending on the jurisdiction.
The reality is, as long as one belongs to a state and as long one holds citizenship of a state, any actions which are considered to be against the interest of the established power will be met with prosecution.
Only the simple fact of being a user of a non KYC/AML exchange and having a big enough volume would be enough to be placed in a black list by most powerful western administrations.
False. Firstly, a country does not have to be assigned to specific borders, that is a subjective social definition you've adopted to describe a country. Secondly, even if a country does need to be assigned to specific borders, one can withdraw land from the country in which it is situated, then start from scratch. Thirdly, countries may and have abandon land leaving it unclaimed. This happened to Liberland. Both countries nearby became jealous and tried to use nasty violence in typical false government fashion rather than respecting other people's basic human rights, reflecting the kind of attitude you allude to, that new countries shouldn't be allowed or the people doing that should be violently assaulted. Fourthly, countries can surely be formed by creating new land in international waters. Fifthly, new countries can be formed in any floating structure on international waters. Sixthly, new countries can be formed in replacement or addition to most Republics by a constitutional amendment to do so. There are likely other ideas I have not thought of as ways to form new countries without any kind of violent insurrection.
