> I wonder if that's the case for everyone, that we can eat dairy products, but it's just not optimal for us

I think it depends a lot on people. Your point about "locally foraged" is good, but you have to take into account your ancestry. For example, I have ancestry in France and Italy, both places that used milk a lot during their history. This gives me better chances than someone with ancestry in Asia or Africa to be lactose tolerant. However in the end it doesn't matter, and the only way to know is to try out yourself and see how you react. For some people, it will improve their health (like how some people improve their health when they stop eating gluten), for others the impact will be negligable or not here at all. Everyone is different.
