Earlier quoted context omitted.
Let people choose if they want to do something, but have a concerted effort to encourage/suggest things that might give them purpose and build a community. Leave them to decide their hours and effort. Maybe someone wants to clean the gutters for their entire block at 6am and then go tinker in the shed for half the day. I'm sure that sounds really lazy, but this concept is working up from a default UBI that is pay-for…
Nobody is going to choose to be a ditch digger without a financial incentive. Most jobs worth doing are unpleasant or difficult. Thats why people pay for the labor! I mean think about it…when was the last time you heard of charity gutter cleaning services? People would much rather enjoy their leisure time on hobbies or with family/friends.
In terms of charity cleaning services, there are people who clean hoarder's houses or landscape unruly yards for free on YouTube... ;)
