So the friction of the wheels IS relevant.
If it weren't, you could walk up to a plane and push it with your own force.

They do a plane pull at Dulles every year.
It takes at least 20 people to pull a plane. They have to overcome the friction.
Maybe I should be more specific - under your scenario, you could tap the plane with your finger and it would roll foward.
