This is different than the gig economy where workers are just pouring hours of their lives into a dead-end job. You never get more efficient at being an Uber driver or a Doordash delivery person. You put in the hours, you get paid, and nothing changes for the rest of your life. (This is certainly true of some non-gig jobs, but at least you get a guaranteed 40 hours of paid work a week, don't have to buy your own supplies, get some paid holidays, and get health insurance.)
In the UK, "homeowners insurance" definitely wouldn't cover you for Airbnb style scenarios, and most "landlords insurance" wouldn't either, e.g. because you needed formal tenancy agreements (e.g. Assured Shorthold Tenancy), no potential for long void periods etc. However, some specialist insurance companies would insure you for Airbnb style scenarios via "holiday let insurance". You'd still need that cover because AirCover only provides insurance for the period while guests are there, i.e. you would still need insurance for break-ins, water leaks, cleaners injuring themselves, etc. in-between guests.
So this supplements rather than replaces your existing insurance. Not sure why this is so prominent on the HN home page because it isn't really something "that good hackers would find interesting" or something "that gratifies one's intellectual curiosity".
Then suddenly "they made it right" and some spokesdrone trumpeted some bullshit like "In this exceptional case we didn't live up to our members / hosts high expectations".
With rare exceptions I also don't see any more advantage compared to staying in a hotel. But to each his own, I suppose.
We rent them for work offsites, family trips, and individual travel. 98% of the time everything goes smoothly.
Therefore most of the time a hotel room is not the right thing for us.
