Imagine you lived in the 1500s and someone showed you two computers. If you had zero prior computer experience, would you pick a touch based computer... or would you pick one where you move some arrow shaped icon with a 2nd device called the mouse.
We're very used to using a mouse, but it's definitely not the most natural way to interact with a computer. It's not easy either. I've seen old people that never could figure out how to double click without moving the cursor 50 pixels from where they wanted to click.
The "natural" way to move a car would be to push it, or maybe attach two horses at the front. The method that we use is quite unnatural.
