I grew up in a location where people always drank raw milk, not from any bizarro beliefs but because for several centuries the way you got your milk was to watch for the cows heading for the barn, then about 30 minutes later send one of the kids over with a pail to collect the milk for the day. It was still warm from the cow, you put it in your fridge or, before electricity, in the basement cool room, and there was never any problem with it. As you say though, industrialisation of the processes and it taking days, weeks, possibly months between squirted-out-of-the-cow and consumption have messed that up.
