Sounds a bit like the currency TIME... every living person gets one second per second.

No more... No less.

Some squander that most valuable of currencies while others spend it wisely. Some is stolen through slavery but even the slave or prisoner is free to an extent in thought and mind.

The more wisely a community spends its time the more value is created.

etc.

We have one basic income already in the form of TIME...

We are Stewards of the time we receive and along with stewardship comes accountability.

Accountability comes in levels and cycles of varying length.

If one doesn't spend time taking care of physical needs, before long the physical body will start to hold one accountable, etc.
