The biggest benefit of pasteurization is extending the shelf life, which is important in an industrialized economy. Dying due to consuming raw milk was not a problem, at least until milk had to be shipped long distances.
Not just distance, but time. If you try to keep milk around for any amount of time after milking the cow, you run risks like Bird Flus and TB and other disease contaminants.
Which is also why in the other direction cheese was invented for time stability of milk.
