You're forgetting about Ageia's PPU.. PhysX was originally meant to run on a PPU, which is even worse than running it on a GPU, because with the former you absolutely had to buy dedicated hardware (and it was slower and more expensive than a GPU as well).

You can run PhysX on a single GPU however, provided it's powerful enough and your graphics settings aren't maxed out.

It is limited to eyecandy because NV want to be unfair to everyone else with its disabling of the function when other GPU makes are in the system & so developers have no choice but to use it for eyecandy only because they would lose out on sales as the game could only be run on NV discrete GPUs & its nothing about being fair if developers could make more by being unfair they would do.
It seems you have deep seated issues with everyday corporate practices
