Something I haven't seen talked about, but seem obvious to me.
This would revitalize so many rural communities that lost or never had a major industry supplying jobs. This would stem the flow of youth out of places like Kansas or Upper Michigan. Can you imagine how much this would mean to communities like this?
This could potentially have some positive secondary effects on the more populated areas as well. SF rent/home prices are insane, and part of the reason is due to the supply of good jobs. With less pressure to relocate to job centers, we could see an easing of demand in those areas. And this is a good counter-argument to those that claim a BI would just results in higher prices for everything.
