As for how much better the EU is:

Is a good example of what can happen here.

If you're relying on a lack of absolute physical proof to support your argument, then I guess you win. Otherwise, there absolutely is evidence that this virus jumped from an animal reservoir local to Hubei, and that the wet markets are perfectly designed to facilitate that process. You're being a bit slippery on this point, but it really isn't the least bit controversial among virologists or epidemiologists.
American-style factory farming of cattle, swine, and poultry, where uncountable animals are crammed together and kept alive with antibiotics, is maybe a valid comparison. America is creating it's own epidemic of antibiotic resistance with the help of these farms (and so is China for that matter). But that does not -- or at least logically should not -- assuage anyone's discomfort with the health hazards of wet markets.
As a vegetarian, I'll happily acknowledge the barbarity and health hazards of factory meat production in the Western world. But this really is a tortured apples-to-oranges thing you're doing here. There is simply no valid comparison between a European meat grocer and a Chinese wet market, and I think you know it.
