Actually that is how I envision people becoming self-reliant in a post-job society. Being jobless and with little money means you got: 1. free time, and 2. needs to fulfil. But jobless people are not without skills - we don't suddenly forget everything we learned when we lose our jobs. There's plenty of skilled people with time and a motive to work.
So why not get services in exchange for services, from jobless person to jobless person? In order to do that we'd need a "human coin". Humans can make a lot of what they need directly - grow food, build houses, repair cars, supervise and educate kids, make clothes. These services should be obtained in the service-for-service system, without money. It leads to a more self-reliant society that doesn't depend on state money, or worse, on transferring money from corporations to people - we all know it's going to be hard to part corporations from their money in the name of social good.
UBI is demeaning and robs people of agency, self-reliance is the exact opposite. Using a "human coin" we could create a marketplace of skills and services without corporate money. Self-reliance should exist at all levels - personal, family, social group, city and country. Each level should be as self-reliant as possible, reducing the need for international commerce and dependence on external factors. When self reliance reaches 100% there would be almost no need to use money, perhaps just for raw materials, so we should be researching new materials that are plentiful and can be produced locally.
