Well, apparently "many people" don't have a basic understanding of biology. The pasteurization process kills all but the thermophilic bacteria which is why you need to culture pasteurized milk. Only one of the two bacteria needed to make yogurt can withstand the process and the rest of the survivors are incapable of out competing our immune system because they are adapted to an entirely different environment. It doesn't matter how many cows produced a batch of milk as long as the temperature is high enough to kill the non-thermophilic microbes. When it comes to food poisoning and regulated dairy products, the vast majority of contaminations are from the bacteria
Staphylococcus aureus, which is so common it can be found on the skin of almost any human being and is easily transfered after pasteurization. A staph infection is peanuts compared to the "ultra-bad" bacteria like
Clostridium botulinum which produces a toxin that is fatal at a concentration on the order of nanograms of toxin per kilogram of body mass (and it certainly can't survive the high temperatures of pasteurization).
Raw milk isn't actually banned in most of the developed world. The EU, for example, has non-binding rules that allow vendors to sell raw milk as long as it is done at a small scale, like your case, where the animals are tested often and the scale of the operation doesn't endanger the health of the average consumer. In most EU countries you can "time share" or own a cow that provides raw milk for your household but you can't openly sell it at a supermarket. Countries like France, where raw milk is culturally preferred (something like 20% of cheeses in France are made from raw milk), have a much much higher incidence of food poisoning from dairy than any of the countries where milk is always pasteurized.
I love raw milk and miss it dearly since I moved to the United States but there is nearly a century of evidence that raw milk at commercial scale is an unacceptable risk to public health. So much so that there isn't a single country in the developed world that doesn't strictly regulate raw milk products and all of them do so for public safety reasons.
