The forests in which people are foraging for mushrooms and berries have no need to optimize for profit. The moment humans get involved in the supply chain, the more the need for some form of (idealized, for sure) oversight from agencies.
Evolution results in other incentives. Beware the assumption that nature is somehow benevolent. It can go either way.
Some mushrooms are poisonous. They evolved to protect themselves from being eaten. On the other hand, some plants evolved so their fruit will be eaten and spread their seeds.
