Your idea of "every basic gesture the human hand can do" proves you're a dog on the internet. The only reason why finger tracking is still a fucking meme is nothing does it properly. The index implementation is nowhere near what true finger tracking needs to be, so it's impossible to demonstrate its potential.

Index controllers, while better than wands, are also massively overpriced.

That stuff is using a bunch of shortcuts and pre-set bindings to control your virtual face and hands. It's like the equivalent of binding the i key on your keyboard to do a "give the finger" animation so you can give the finger by moving your middle finger on the keyboard.

You could have a canned animation for your lower body, and you could manually set VRChat to a seated mode, but that'll limit you to the pre-scripted moves that were programmed in. Full body tracking gives you real tracking that can do anything.
