One can start by minimizing their interaction with government entities, and resteicting information given to corporations. Whenever some gov/corp representative wants my physical address, and won't accept my mailing address, I question them. "Do you plan on visiting me? I don't want you at my house."
Of course, sometimes I want them to have my physical address. Deliveries being a good example. If law enforcement is dealing with me in a legal manner, and it's required for that particular procedure, I'll give it. My DMV won't send me a sticker to update my address, and it's been that way for years. It's created a few problems, but nothing serious, and most reps just try to work with me anyway. It's also created funny situations, and has created massive comfort for me in others. Currently, I can't prove my physical address. Someone has to either take my word for it, assume my rental contract is still in effect, or take my word that my landlord is my landlord (and take their word for it).
That's just an example of minimizing address exposure. Another is to run a private business. This means your customers must become members, and membership has a criteria (not anyone can join). Since you and your customers are exercising the right to private free association, you don't have to adhere to codes, regulations, statutes, etc. Those are all aspects of the legal system, not laws. As long as you follow laws (not harming anyone, stealing, violating someone's property, etc), you are free to make whatever agreements you want. Companies operating publicly must follow all laws and all legal requirements, which is sometimes impossible. This type of private business is known as a Private Membership Association, and has been upheld in US courts, even for people not following legal requirements related to Covid.
Technology is a sticky matter. If you have Graphene (which only uses NSA phones), you're still being spied on by everyone else's phone. Turning off phones is just a parlor trick on yourself. I have Gorilla tape over my selfie camera, and usually have my phone laying down on the other lenses, when I'm doing something at home that doesn't require a phone, it's sitting in another room. To add more privacy, turn on a radio to jam the microphone. Quit using Google for logins. Quit using big tech email. Of course, ditch centralized apps. Sometimes I still use Google maps, but I minimize exposure by using it in a browser, and use it like a paper map instead of asking it to show me routes, etc.
The goal isn't to go completely off-grid. Well, actually that is an end-goal. Until then, it's nearly impossible to quit using all tech, quit filling out forms, etc without making your life really messy. Besides, if you vanish off their radar too quickly, you will draw their attention.
I probably have more suggestions, but it's time to eat dinner. Know that you are born free. You are allowed to do whatever you want responsibly. When you are solid in those beliefs, and have 100% trust/faith in them, you will be able to defend your rights. They want to scare you into bending, because that weak power is the only one they can really use, and it takes your compliance to work.
