> No they don't ban vegetables with the wrong dimensions, they just put them in a lower quality class that no supermarkets will buy

Except they do. The premium supermarkets don't, but immigrant shops, etc. do buy class II veggies. It's the supermarkets's own choice what class they want to buy. Some deliberately buy even lower-class ones and market them (justifiably, I believe) as good for the environment as compared to discarding them.
