Wrong on many levels, already refuted by many commentors.

If food needs to be subsidized, subsidize it directly. Already done with food stamps, etc. You can apply here: https://www.usa.gov/food-stamps

If food gets costlier, people will eat less and it will reduce obesity, metabolic syndrome and save trillions of dollars in healthcare costs every year. The poor, who you seem to be so concerned about, can't afford the costliest healthcare on the planet.

> food gets costlier, people will eat less

Wrong. As food gets costlier, people shift eating habits from healthier but more expensive food to cheaper ultra-processed food. There are similarities elsewhere, like the iron law of prohibition: making opium more difficult to sell shifted the market to heroin, and eventually to fentanyl.
