What is the actionable "fix", though? I mean: there are very real questions to be asked about gain-of-function research. There are other questions to be asked about standards for lab safety. But we should be asking these questions anyway, especially now that we've seen how devastating a real pandemic can be.
Whatever happened in Wuhan it seems like the primary evidence is gone now. Trading in unverifiable theories about a lab leak is only useful insofar is that it kicks the ball forward on these issues. However the risk here is that these debates will make the issues controversial and politicized in ways that actually make safety improvements more difficult and not less.
One actionable fix is not putting virus labs in big cities (just like Nuclear and industrial plants), the other is stronger regulation of animal markets. Both make sense independent of where the virus originated from.
