if there is a fast and intense supply chain disruption what would be more helpful than having a gun

I'm thinking like April 2020 but worse. I can't own a gun bc I'm depressed. what is some cool prepper shit I can get in a go bag for a catastrophic national or local event. . I got started with a shitty solar powered portable charger , a pocket knife and a rechargeable flash light. i think im missing water filtration. can I get a sword. can I get a sailboat.
