No. We should consider all non-impossible hypotheses, weighted by their prior probabilities. What's dangerous is to proceed with sanctions against china without having an airtight case (with multiple cross-consistent supporting data inspecting by many parties). Nobody has made an airtight case that the virus was human-engineered (for whatever reason) or leaked (intentionally or accidentally). ANd it's most likely any evidence that did exist has been scrubbed.

However, that's all speculation, not fact.
