I guess another way of thinking about it is that cutting taxes (in theory) leads to increased consumer spending which equates to a increase in demand. In supply constrained environments like what we see today increases in demand will result in increases in price. Widespread increases in price is inflation. Idk it seems pretty intuitive to me and is a pretty common theory, for instance its mentioned here https://www.forbes.com/sites/howardgleckman/2022/06/02/shoul...
