I think what differentiates hopping between airbnbs and being homeless is whether you have the financial means to live in more stable conditions. Living in Airbnb’s could mean you’re a luxury traveler spending $100k+ year on accommodation or it could mean you can only pay for shelter on a day to day basis (ie you hustle for cash every day, convert it to some electronic format, and pay rent on a daily basis). There’s also the case where you can afford a 1room Airbnb in an area but not rent, which I also wouldn’t call homelessness
