As a digital nomad, I have no long-term home. I literally live in Airbnbs. I tried finding a policy to cover me, but none exists. Policies also vary a lot with burglaries - eg some require signs of forced entry.
Hmmm I wonder if in that case a good travel insurance would work. You are staying in those places temporarily so I'd argue it's travel.
Have you considered starting this up as a business? Surely there's a market for it, and the claims data alone would make you a valuable acquisition target.
