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-no-job.
I can imagine loads of tasks or jobs that would be quite pleasant if it weren't for stressing over efficiency or business admin.
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.
Why would there not still be gutter cleaning or ditch digging companies? Or people cleaning their own gutters? I'm not familiar with UBI proposals that do away with traditional enterprises; it's generally suggested as raising the floor. People would have more time to clean their own gutters or use the money they receive to pay someone else.
In terms of charity cleaning services, there are people who clean hoarder's houses or landscape unruly yards for free on YouTube... ;)
I'm talking about gutters on the street, beside the kerb. I thought this was implied after I said "keeping your block clean by sweeping and mulching". You routinely see older people in Asia sweeping and raking a communal area if you get up early to walk. There's a (probably obsessive-compulsive) 60 yo guy a few houses down from me in Australia who might've retired early and now goes around raking verges and cleaning the footpath/gutters meticulously. Near my office, there's a woman who bakes bread for the joy of it and sells it at-cost via an honour-box in a sidestreet. She also turns verges and front yards (with owners' permissions) into a community vegetable garden. If others were given an opportunity equivalent to early retirement, these sorts of things might be more common.
As for why: for purpose, for praise, for community, for mental health, for trade/contribution, for skill building, etc. Loads of examples of this already. Maybe none of these things are attractive to you but I don't think that's universal.
Like I said, it's just trying to add to the default UBI, not getting everyone volunteering in their community or else.
Most retirees, early or not, do not contribute to society with their labor nearly as much as they did during their working years. What makes us think that UBI beneficiaries would be any different?
