I present a counter question:
Why, out of a dozen solutions to any given problem, do you often present legislation as the only option?
Legislation is essentially forcing people to do something on pain of punishment by the government.
I would present the opposite argument - that if we stopped passing legislation that forced people to buy globally, communities would develop their own food sources locally. Centralized food production and distribution is a very outdated 19th-20th century model and will not be sufficient for the worlds growing population - as we saw in COVID when the Global supply chain started to suffer the slightest strain. It also provides an inferior (but cheap) product.
