Gain of function research outside of hyper-secure settings is, frankly, idiotic. It’s massively more dangerous than criticality experiments because of the potential for exponential spread.

From the beginning gain of function research has been done at levels as low as BSL-2, and this article claims the Bat Lady said that all their coronavirus research prior to the pandemic was done at BSL-2 or -3 levels. The Wuhan Institute of Virology's BSL-4 lab would likely be booked up for research known to be very dangerous, and as you go up in levels it's more and more inconvenient to get anything done from the physical protections (there are also supposed to be biological ones).

Plus it appears that the lab was poorly run: She noted that a September 2019 paper in an academic journal by the director of the WIV’s BSL-4 laboratory, Yuan Zhiming, had outlined safety deficiencies in China’s labs. “Maintenance cost is generally neglected,” he had written. “Some BSL-3 laboratories run on extremely minimal operational costs or in some cases none at all.”
