This is literally not true.
Most virologists say the way this virus works is unlike anything they’ve seen or expected so they can’t imagine how a human would have engineered it. Why do you think your feeling about the virus’s level of adaptation trumps the experts opinions?
1) Citation on "most" please. The world is a big place, so you will be able to find a citation for any opinion. If you are going to say "most" then please back it up with a source.
2) gain-of-function research doesn't require a human to engineer a new virus. It is a way to essentially speed up evolution and allow nature to do the heavy lifting. You're arguing points that no on here is making.
It's a long article so I don't expect you to find the argument in it; it highlights the work of Alina Chan who compared a fast mutation rate of SARS-CoV as it better adapted itself to human to SARS-CoV-2. Here are titles of three of them I've saved but not read, May through September of last year:
SARS-CoV-2 is well adapted for humans. What does this mean for re-emergence?
Single source of pangolin CoVs with a near identical Spike RBD to SARS-CoV-2
COVID-19 CG: Tracking SARS-CoV-2 mutations by locations and dates of interest
