I mean obviously you need less energy to move things around. We spend an enormous amount of energy to move things around on earth.

1/6th of Earth gravity is even better.

Short term: a wonderful tourist attraction. You can nearly fly.

Long term: people with muscular / bone disabilities who cannot withstand Earth gravity. An interesting retiring home (for a narrow wealthy set, of course).

Who is going to pay to fly these sickly retirees to the moon, and then continuous supply them with resources that are literally free on Earth (ie air)? Medicare?

Moreover, if they struggle with earth gravity, how will they survive launch and landing?

By using the space elevator, of course!

For a spacefaring civilization reliant upon chemical rockets, less gravity is better. Point being Mars is a better place for such a civilization, not earth.
