My comparison is UBI reality.
All other "UBI studies" are 100% enabled by their surrounding market economies. Works great when you have that supporting infrastructure.
Not so much without.
It's always, "yeah OUR way of doing it won't be anything like that"

Until the inevitable inflation hits. Then UBI yesterday isn't "enough" for today, then the demand is more for tomorrow.
Wholly unsustainable without 100% "free" robotic task handlers.
