What is the point of a universal basic income if the value of the currency constantly changes?

Ex: if I receive $2000/month and the cost of bread doubles, the value of that $2000 decreases. It means I have to go out and find a job to make extra money to buy bread. But the whole point is that I don't have to go out and find a job.<br><br>Say the cost of bread doubles, and the government gives me $4000/month now. Then the value of the money decreases so the price of bread doubles again. Governments just keep raising the amount of money but they also keep causing inflation. So you are right where you started. And in the end the government would have to raise the amount of money they give you but exponentially more because of the inflation.
