I'm a pretty simple guy. I enjoy eating macaroni and cheese. I like to eat mine with a fork. My friend prefers a spoon. It would seem to me that, rationally, a spoon would be a more efficient tool for macaroni consumption. Using a spoon, one could scoop up more macaroni with less effort, and finish eating more quickly. And yet I use a fork. Why? Because eating efficiency is not my concern? Certainly not; I shovel as much macaroni into my mouth as I can get onto the fork. So why? Why do I insist on eating with a fork? The answer, of course, is simple. I eat with a fork because I want to. I like eating with the fork.
So your problem is thus: how do you convince me to use the spoon instead?
On the other hand, I suppose a spork would provide even more efficiency...
