Well of course, the racoon dogs et al all come in via human transport.
Testing infrastructure was poor, and maybe it still is. Chinese government interest was not in finding facts, but in taking action to 'solve the problem'. It's hard to find facts when the people with power just want the problem to go away. IMHO, that doesn't weigh in favor of either explaination. The wuhan local government and the chinese national government would have likely taken the same actions regardless of the source, because they're both not very interested in facts.
US health authorities pushing on the market theory are just doing their typical behavior of taking what little information is available and pushing it with no nuance. I enjoyed seeing the cdc stickers telling me not to use a mask out in public areas when the cdc was requiring them; the congitive dissonance was so palpable.
They prioritized healthcare workers to wear masks
Not a single positive animal sample at the market, or anywhere else. Not a single one. That raccoon dog "evidence" shows that raccoon dogs were at the market, in the same place where the virus was found. That's all.
Humans brought the virus to the market. It's screamingly obvious and always has been.
