Preparing for homelessness survival

Obviously day X may never come, but I am starting to plan/think for it nonetheless.
In the case that we need to just get out of the cities and start figuring out survival on the outer edges of society, what would we need?

Weight is a huge concern, so we would need to bring/pack as little as necessary.

- High quality lightweight tent
- Robust hiking all weather clothes, gloves, socks, hats, etc
- Good shoes
- Outdoors basics like water filter, knife, kindling rod, compass, laminated maps of the area
- some lighters
- bottles to store water
- first aid kit

What else? What am I missing? We do hike a fair bit but are by no means super outdoorsy people like probably most on here.
