I’m not American, but for basic essentials, creating an online local network seems like a good idea to me. You could use it to share free clothes, food, seeds, and so on, and perhaps help run or boost local projects. The rich absolutely hate trading or gifting, so that makes it even better.
I think a huge one is also encouraging friends and family onto platforms and apps/programs that don’t sell your data. That way, you have a safe place to chat and organize without the government watching and collecting info, and without algorithms trying to bury movements.
Use trusted encrypted platforms for important chats.
Just a guess here, but it could be one part being in an air-tight sealed container, and one part being stored in a cool location. The porous nature of clay might also be an advantage somehow too.
