Do we have a quantitative measurement for “all the time”? We have in living memory the emergence of HIV which presumably also came from an animal host initially. And the previous 2 variants of covid which were not very contagious.
Please note I am not “convinced” either way. I am just noting a gain of function experiment is a specific set of conditions that might take nature decades to centuries to replicate by chance. It is a plausible method for the virus evolving. The other way being that lab field workers are going to collect more exotic specimens than commercial meat sellers, going deeper into caves,etc. All it would have taken is a mistake or counterfeit equipment such as HEPA filters, a problem that appears to be more common with current Chinese industries than in equipment from more mature name brand western companies.
