If it gets so bad that you need tools for building shelter, you are absolutely fucked unless you already have farmland and can defend it. People are massively ignorant about how difficult it is to live off the land if you don’t have experience in it and a lot of supplies and knowledge accumulated. It takes acres of crops and animals to support a couple people. It takes months or even years to make that land productive enough to keep you barely alive. Then if you have hard winters you better hope you have a stockpile.

Financial collapse is one thing, but a total societal/technological collapse would be bad in orders of magnitude that I don’t even know how to describe it.
