This might sound radical, but I've always thought it would make sense to bring back some of the programs from the New Deal as part of UBI. In the US and Canada, infrastructure is crumbling. As part of your UBI (if you can't or choose not to work) maybe people should spend a week a month working for the good of their society. It's not perfect but if there is a job skills/training component of these things, and exposure to people of all types it would be good for a lot of people.
