My reasoning has been: new viruses jump from other animals all the time, it has happened in the past, we don't have any reason to think that is not the case this time. It's not surprising at all that it appear in the most populated country in the world.
But after learning about that lab, I have to think: that a new corona-virus appears in the wild a few kilometers out of one of the few labs specialized in corona-virus have to be explained.
Personally, I can't just disregard that because it's not politically convenient.
Political convenience aside, the question whther the SARS-Cov-2 escaped from a lab or not doesn't seem to be that important in finding a solution / cure / vaccine. All it does is playing the blame game and distract from the real problems.
