If you try to fight laws you will lose unless you have the at least 100k of people behind you.
Okay, very tough question due to the fact that I have at least 20k invested.
When it comes to survival I break it down into 4 categories.
Food
Water
Shelter
Security
That would be about $50 per category.
Food- buy seeds and jars. Canning your own food is a good start. When you buy groceries, make sure when you get your fruit they are the ones with seeds already in them. Also YouTube how to make a snare for catching small game.
Water- I would buy the biggest water tank I could with 50 dollars. Fill it up and forget about it till you need it
Shelter- I'm sure you have a home, purchase extra locks, flash lights, and batteries.
Security- actually this is probably the easiest prep. If you have a knife and foresty near by the type of weapons you can make are endless. (Spears, beat sticks, bow and arrows, ect. )
For those of you who are very experienced, I do realize I left a lot of stuff off. That's because if I only had 200 dollars to work with that's where I would start
