Indeed. I think this is huge. To me, this is one of the most attractive things about basic income. Someone receiving basic income (and protected by universal health care) can effectively do whatever they want. That includes playing video games all day, but it also includes working full-time on something interesting to them. Maybe it will be profitable, maybe it'll simply make them a more interesting (and maybe even more employable) person.

A basic job tends to discourage mobility in all the ways a normal job does. A basic income encourages mobility because you have time to do anything... including invent something or go back to school (or use online courses) to learn a totally new field. Or even just take a break to recharge.

I'd love to model this, but I have no clue how. Perhaps a normal distribution of a change in a person's ability to produce value when taking basic income and not working. Some people will drastically decrease their ability to produce value, some people will drastically increase it. Most, I suspect, will somewhat increase it and then get back to work.
