UBI is just wealth flowing from the government to all individuals. The goal is redistribution. As a government, you can explicitly specify who wealth is being taken from by paying for UBI in taxes. If you don't raise taxes to balance the budget, your choice is between kicking the can down the road with debt or printing money. Printing money is really just another form of redistribution drawn from the wealth of everyone holding that currency. Naturally, doing so can lead to a crisis of confidence where the value of the currency collapses as people flee to other assets that are less likely to be devalued.

UBI, like any government spending, needs to be paid for. By taxes or financial disaster. I prefer taxes, personally.
