Point is, that's the way all humans lived up until the last hundred years or so.

Excuse me. That is utter and complete garbage. Read contemporary literature of, say 100 years ago, or 220 years ago.

I bet that any child in the pioneer west who ran to his mom at the age of three and yanked down her shirt to nurse while she was busy working, and any mother who tolerated it, would not have lasted long.

In any but the most hungry of places, it can only be a power dynamic on the part of either or both both kid and parent. The kid certainly doesn't need to nurse physiologically at the age of three.
