Then use a pole that is strong enough to eliminate this problem.

I would imagine that what the five year old who asked wanted was an intuitive sense of how far away the moon is. My answer would have been far less interesting. I would assume a reasonable rate at which a child slides down a pole, say 1 meter per second, multiplied by roughly 384,000km from the moon to Earth, and it would take a little over 12 years.

Doing so would have consequences.

Probably bad ones.
