Marketplace of ideas is just measuring the average of views at best and fringe views may on occasion be valid, or not. It is also gameable by promoting "truthy" or plausible explanations with no data behind them.
In this case, it is irrelevant what the source of the pandemic was, securing the labs doing viral research to BSL-4 is prudent. The only issue faced is one of funding, which is vastly insufficient to maintain these facilities. Or at least placement in remote locations with quarantine in place to prevent leaks.
Data only weakly suggests a composite and does not categorically exclude natural origin. Leak of a natural or modified virus would be just as bad. Same if it's from consumption of rare animals sent from remote places or research on the samples from them. In either case, only different degree of luck is required for a pandemic.
