If it was natural, which is by far the most likely scenario, what could've been done? Coronaviruses are extremely common in bats and other animals, and transmissions from animals to humans is just a matter of time, and just more likely if you have more people. In particular people who eat exotic animals and have low sanitary standards like it's the case around rural China. There aren't any good solutions that I can think of apart from exterminating all natural hosts. Otherwise we're going to have more of those nasty things move from other mammals to humans over time.
I think whenever we come out of this, there's going to be a divide among the people about finding out about origins of the virus and there's going to be a lot of finger pointing. There will be one group that just wants to move on from it and continue living their lives and there will be people that feel that there's some big cover-up because their government didn't look to get to the bottom of all of this. And even once it's done, the virus will continue to be a political topic.
