> By this logic, why doesn't Congress illegalize travel? Is that going to reduce the cost of travel? Will that reduce CPI, which measures prices, not demand?

Hey, you asked for a "common sense explanation" how the policy works, and people gave it to you. If your intention was "I want to debate unrealistic what-ifs with as many people as possible," then you could have made yourself clear in the first question.

Because then the money just gets spent in other places shifting around the inflation.

If person A holds on to the borrowed cash and doesn't spend it, that money doesn't circulate (the velocity of money decreases).

If person A doesn't take the loan, there is less money in the system (money supply is reduced).

If there's less money circulating, people won't "bid-up" the prices of food and gas as much, reducing their price (assuming constant supply of food and gas).
