@Nikolay26 There's a big difference between couch-surfing and a shared-home listing on Airbnb.
Those who are couch-surfers and those who open their homes to them are just liking to meet people from all over and the hosts are usually travelers themselves and like to couch-surf themselves when traveling. No payment is expected or received, neither is any special treatment or amenities. You very much have to fit in with the routine of the home.
While many home-sharing hosts also do it in part because they enjoy hosting and like meeting people from all over, guests usually have a private room, often a private bathroom, share the kitchen or have no kitchen privileges, or even have an entire suite in a host's home. Basic amenities are expected and provided. As a host who rents a private room/bathroom in my home and share the kitchen with my guests, I do tend to have quite bit of interaction with my guests, but that is pretty much up to them. Some are out and about most of the time and we don't see much of each other. Some are quite sociable, some tend to just want privacy. Some make use of the kitchen, some don't. Some I'll have long conversations with over coffee or a bottle of wine, some not. Some I'll take to a secluded beach they'd never know about, some have all their days full and planned.
It's quite true that some guests are just not suited to a shared-home listing, and those should book hotel rooms or entire place listings. But most hosts with shared home listings do not impose themselves upon guests nor expect them to hang out with them as if they were old friends. We play it by ear, guaging the sociability of the guest.
There are many guests who enjoy booking home-shared listings- they feel safer, they get the local low-down from hosts about places they'd never know about as a tourist, like cool little restaurants or nice nature walks or running trails, out-of-the-way shops with unusual offerings, etc.
If having to be friendly and interact at least a bit with a host is something you don't enjoy, then you should definitely not book shared-home listings.
