Just doing nothing isn't great for the "human spirit", but UBI doesn't mean people can't find their own goals to pursue. The idea of something where people are not longer required to work to survive is hard to accept since many people haven't seriously considered how they could meaning outside of their careers
counterpoint : my father had realistic expectations for what he wanted to do post-retirement.
what actually happened was that he sat around purposeless because it turns out that the motivation of producing a paycheck or product was actually the reason he did things. He stopped showering, became depressed, and neglected his health.
And this isn't an uncommon reaction to the open-ended 'free-form' life post-retirement. Some people very realistically need to have some level of structure imposed on their life or otherwise be taught how to create that structure themselves. I think this will be a very real problem whenever UBI gets closer to reality.
