> This one at least, and probably all of them is stuff that already happens

Yes. The system incentives against it, yet and it still happens. Redesign the system so that it incentivizes for it and it'll happen way, way more.

The idea that the idle poor are running around "improving their communities is obviously bullshit. The poor already work fewer hours per person, and their communities are universally the most neglected.

> UBI compensates all work

Capitalism compensates work that someone is willing to pay for--i.e. work that consumers find valuable. UBI compensates "work" playing video games and sleeping until noon. Pretending that the latter is more moral than the former is positively asinine.
