No, you can do a UBI that keeps the money supply the same, and use it as a way to stabilize the economy. With a $2000/mo UBI, 50% flat tax on other income, 25% VAT, phase it in by doing 10% of that the first year (and 90% of your current taxes, 90% of current support payments), second year 20% and 80%, so the impact isn't too disruptive. Adjust the flat tax rate as the Federal budget changed (a spending bill is automatically a tax bill as well). Adjust the VAT to control inflation.
