No one argues that it is impossible for the virus to emerge from the natural causes. It is equally possible that emerged from the lab, there might be a variety of reasons for that, say similar to pilot-suicides: a disgruntled employee took it out of lab or something. There is nothing political in such a hypothesis; quite opposite, to accuse people who consider it probable of some political motivation is political by itself (based upon hatred of Trump for example).
