IMO it is not possible. The world has changed. Until modernity, people made connections out of economic necessity. Either you get a wife or have fun farming by yourself - literally it doesn't work so you die. Either you're friends with the baker or you don't get bread or get absolute shittiest-quality goods and you die. And so on. Shut-ins didn't exist because it was physically impossible to survive without leaving your room. No UberEats, no Amazon Prime, no remote work, no internet.

When the economic necessity to form relationships with others disappeared, the naked truth was exposed - most people don't fucking like each other. Yes, when you're starving to death you'll be friends with the guy who has potatoes, but when you can buy the damn potatoes yourself in the supermarket, you're not going to tolerate his smelly ass.

Most friendships form over common participation in a project. Doing something together, knowing that you have to put up with the other one to achieve higher goals. Without those goals, there are no incentives to deal with others. And what goals am I supposed to have if by doing nothing I already have a roof above my head, full fridge, clean house, and an entire library of video games?

Think about the main message of feminism: "Girl, you can make it in life without a man. Don't settle for an aggressive alcoholic just because that's the only option. You can do it yourself.". It perfectly captures how forming relationships turned from an asset into a liability.
