I can definitely see your point its like the final phase of fiat where you kind of admit its worthless so just everyone try to spend it as fast as you can and lets see if we can keep kicking the can down the road as we have controlled consumption and production with rules based money
Like you say the money becomes even more political and creates more weird incentives and ways to game the system, that have unintended consequences. Right now the money is corrupt but not to a point where critical operations fail like growing food or generating energy, thats my real worry for UBI maybe its far fetched but even just watching the crazy stuff people are willing to do to get government grants and contracts in the current system, makes me feel like UBI will be like that x10000
I think all of us here are aware of Bitcoins game theory pushing a migration but Im not yet convinced a large enough minority gets it yet, to drive change, the idea of free money is so strong thats why shitcoins do so well for a brief period.
Governments can do what shitcoins do for even longer with UBI, but lets see, I guess more fiat pain can convince people
