Music equipment insurance isn’t actually that expensive, and it should cover the equipment wherever it’s at (on the road / at home / in the studio), natural disasters, theft, etc.
I also need to do it, it’s usually a yearly payment.
Some friends use these folks: https://www.musicproinsurance.com/ but there are others people swear by.
Renters insurance generally leaves a lot of coverage gaps.
edit: I think my main psychological hurdle is inventorying everything :P, but I’m gonna regret waiting when I get robbed or flattened by an earthquake. IIRC a friend paid around ~$250 for 20-30k of stuff? Very roughly in that neighborhood.
