That's a pretty counter-intuitive statement.

It's like making fun of modern humans for not being able to light their own fire with two sticks, when they lose their lighter wile camping.

Or for someone to not know how to sew a rip in their clothes, when the clothing store is closed. Etc.

Not sure how I’m making fun of anything, training wheels inherent purpose is to train you to ride a bike without them. A lighter isn’t meant to teach you how to spontaneously light fires once it’s out of fuel, nor is dropping off clothes at a clothing store going to teach you how to sew.

You don't need to learn to ride a bike if you prefer motorcycles.
