I get why people might feel this impulse, but they should realize that it follows the same logic as tariffs. You do not gain by closing yourself off from the world. Having the choice among the best products in the world is prosperity. Whether you restrain yourself by choice or by force, it's the same zero-sum mindset. Free trade, with some exceptions for fledgling industries, is one of the rare cases that makes everyone better off. Unfortunately, even the simplest explanation [0] is a bit unintuitive, which may explain why trade restrictions are one of the few things popular among parts of the left and the right.
