According to this article/study
A space elevator to the moon could be doable
Its central element is a cable that would be anchored to the moon and span more than 200,000 miles to a point above Earth's surface — perhaps an orbit about 27,000 miles from our planet.
Future space travelers would use a spacecraft to fly from Earth to the end of the dangling cable, which would be held taut by Earth's gravity, and then transfer to solar-powered robotic vehicles that would climb up the cable to the moon
This topic in Space SE provides the cost now of sending to the moon or to lunar orbit, which says to be $1.2M/kg -- $198K/kg respectively
What is the marginal cost of landing on the Moon?
How much would reduce the cost of sending kgs to the moon sending the packages to the lunar space elevator endpoint at 27,000 miles of Earth?
