It makes sense. Where else would Vegapunk be trying to go with a warping machine.
And in Enels cover story, there was that old dude from Vegapunk's home island, whose animatronics went to the moon, after he died. And Enel seemed to have found an Ancient civilization on the moon, which is definitely something Vegapunk would be interested in.
And the cherry on top, is it opens up a way for Enel to get back to Earth if there is warping technology that connects the Moon to the Earth.
