You could, for orders of magnitude more compute than reading a magnetic encoder (my assumption at how they estimate it)

Sure, but not more than what you're already spending on transforming the image. And it's not like these devices are exactly lacking in horsepower.

This is trivially broken by people who affix some type of cover over the camera. I do this on the off chance some errant application thinks it deserves to take pictures of my environment.

If someone covers the camera, the feature isn't relevant since it requires the camera to see your desk

Isn't the desktop view is produced from the iPhone camera capture, not from from the MacBook's camera?

If you have a new Macbook the built-in camera does it

I'm typing on a 2024 Macbook Pro. Is that sufficiently new? I don't see how it would work, practically. The only camera is the user-facing one. If the screen were tilted down toward the desk, I'd have to kneel down to see it.

But compute is cheaper for the manufacturer than adding a sensor (parts & labor, and it adds up over millions). Someone must've done the math.
