Learn how to grow food and filter water, those skills would've been useful for you anyway (honestly they should be known by literally everyone, but oh well, such is life, everyone is ignorant). Don't be a city bugman, own land and use it. Remember that police and all the army is still merely a fraction of the population of any given country. They physically CANNOT directly control everyone, they MUST do resource management. Going after some "literally-who" farmer isn't worth their resources, they have to min-max in order to stay in power. There's actually plenty of ways to stay under the radar of even really oppressive countries (maybe with the exception of shit like China, North Korea and those small weird despotic countries). But you seriously mustn't live in a city for that. And if you're still planning on using technology like internet:

first: use it LESS

second: learn as much as you can about it, always choose open source things that allow for as much customization and tweaking as possible

If you're a city nigger, start with some potted plants when it comes to growing food. No they'll never be able to feed you, but you can learn some absolute basics with them.

You want freedom? No, what you actually want is independence.

Step 1: own land.

Step 2: learn what you depend on for your life and how you can eliminate those things so that you only rely on yourself (or as much as possible)

You can produce over 10x more food than you could ever eat, you just have to learn how. It's not communism YET, take advantage of that. If you truly believe everything is falling down the brace for impact. And "brace for impact" doesn't mean posting shit online, it means learning how to be as self sufficient as possible.

If you want to understand the world more and get some hope read this: http://gojolaw.com/wordpress1/wp-content/uploads/2019/07/Theory-of-Power.pdf (if the link is dead, just look up "theory of power Jeff Vail".)
