People need variety in their diet, but they almost certainly do not need things like bananas, you can, in most places around the world, get nutritionally complete diets from locally grown sources, which will often be of higher quality, tastier and usually cheaper. I certainly can’t think of anything that I need, that couldn’t be bought at a farmers market. Now I can imagine some dietary restrictions and choices will have those needs, but restrictions can’t be helped and choices are probably more environmentally conscious anyway (vegetarians, vegans).

Local does not have to be in your rural community. Something that is trucked to your local store a hundred(s) miles is certainly better than something that was trucked to a port, shipped halfway across the globe, and trucked again.

“Doing something that Joe isn’t doing is not worth it” is a bad mindset, especially since Joe might not be doing it for the same reason. You can’t expect everyone to start doing it the same day. The more people buy local, the cheaper it becomes to buy locally and less profitable to import.

Regulations would be great, but Id prefer living in a society that can self regulate.
