I never claimed that it wasn’t D’Oraisa. However, an Issur Aseh has a lot more reasons not to be Machmir than a Lav. Your third point is a big problem for Rav Elyashiv’s Heter to drink milk. I will try and find that Rosh. He doesn’t say it is Assur. He says that it is still okay with Rov even though there isn’t Shishim. It is against what is brought down in Shulchan Aruch. Your analogy to the meat doesn’t work because there is no Kol D’Parish Miruba Parish. Since it is all milked together nothing is Parush. It’s all together. It would be like a soup that we find that we know is mixed together from all 10 stores. We know that if we found a soup Stam it would be Muttar because of Rov. But we also know that this soup has 10% not-Kosher soup mixed in. Any individual pot of soup would be okay (just like any individual bucket or glass of milk from a single cow). But once all the soup is combined together and we know for a fact that 10% of it isn’t Kosher (even if we don’t know for whatever reason which of the stores wasn’t Kosher) then the Issur isn’t Bateil and you wouldn’t be allowed to eat it.
