Easy for some, harder for others. I think driving a car is pretty easy too but
its still requires a learner permit at minimum (requiring a licensed driver present)
to operate the vehicle on any public roads. I have seen licensed pilots unable
to put an airplane squarely into a tiedown spot.... repeatedly. Perhaps they lack
the skill to really master the plane (scarey), perhaps they were poorly trained....

The reason is simple.. until you have reached a point of demonstrating ability
to safely master the control of the [insert whatever machine you want in here]
and have received a license/signoff/endorsement for solo operation you are a
potential accident... no matter how "easy" it seems to some people, or how smart
you think you are.

I'm sure Peter Duniho (being the most capable and knowledgable pilot to ever
have taken flight) could safely taxi an F-15 when he was six with 10 minutes
of training. For most people, learning to taxi an airplane SAFELY takes some
training and experience.
