If you want to press a reset button and switch to resource based I don't think you'd hear those billionaires supporting you as they'd suddenly lose a lot of their power and wealth.

Many of them have a ton of investments. And I am pretty sure I dont want the same thing those billionaires want, just because they call their ideas "UBI". Same for me with many people who called their ideas communism ;).

Also if the people in power will never ever make a fair deal with the world, we are forced to be violent and will most likely lose. I believe as well that all states and big corps are corrupted and will fight to keep the status quo, but that should not stop us from developing alternatives to our current society.
