Executing other actions isn't a feedback loop like moving the mouse pointer; for the mouse pointer you need the feedback from the system before you even get to an actual action. You can press keys on a keyboard blindly, if it doesn't matter where you can even click blindly, but you can't position the pointer blindly. It's closed loop vs. open loop.

Of course you can position the pointer blindly, it's not moving in an unpredictable way.

If you genuinely believe that, I invite you to look up the linearity specification on a few mice and trackpoints and post them here.

And if you look at your motor neurons under a microscope it all looks like chaos too.
