It doesn't seem like a strawman to me. The money has to come from somewhere or else mass inflation will happen instantaneously. The number of goods and services that exists is finite. Giving people free money which removes their burden of supplying value to others will not only fatally harm the buying power of the dollar but it will actually reduce the number of goods and services available which will have the opposite affect than intended. UBI will fail spectacularly if implemented at any meaningful scale.
