I worked in many different industries and later in finance and blockchain industry for years so I do know what I’m talking about. That said, you’re correct in saying that the dollar is backed by nothing. They keep printing more and loaning it out at near 0% interest to huge corporations who circulate it among themselves and use it to pay off each other’s debts (to inflate their revenue numbers). Not to mention governments handing out huge multi-billion dollar contracts to big corporations in exchange pointless projects (also inflates revenues). UBI doesn’t change the fact that money is still being printed, the difference is that it will go to individuals instead of big corporations.
