Instead of trying to deal with all the problems associated with constructing a space elevator here on earth. The moon would be an excellent testing ground for building future space elevators on earth or at Mars. It would also make getting to and from the surface of the moon very cheap in the long run.

My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events.

Wouldn't it cost more to be able to have oxygen on the moon as to be able to build the elevator?

I'm taking a liberty here but...
Do you mean that there is no reason to have a space elevator since the Moon has no Atmosphere?

I'm just saying the construction site on the moon would cost more than on earth because of the lack of oxygen on the moon to be able to build the elevator.

OK.
As i understand it, we don't at present have a way of producing materials strong enough to build an elevator on Earth.
Carbon nanotubes may be strong enough, but we don't know how to bond them, or make them into long enough strands.
Because of the Moon's low gravity it might be possible to design a Moon elevator that doesn't fail using materials we have.

Good point.

Wouldn't there be problems due to the Moon being Tidal Locked, not being a true sphere and that the Moon's equatorial plane does not match that of the Earth.

So that the "Object" the elevator would go to would never be in a stable position.

A Space-Elevator, in theory, relies on a stabilizing counter-mass, beyond the
Stationary-Orbit, to maintain tension in the cable.
The simplest solution is a very strong cable that tethers a very large mass
close to Earth, anchored on the Moon.
I suspect that this is over-engineering a problem.
Anything you send up the Elevator still needs to go somewhere, which would need
propulsion to achieve vectors that could have been imparted by a linear-accelerator on the Moon.

Ionized propulsion would be a good solution to that.

Ionized propulsion would be a good solution to that.

i prefer anti-matter catalyzed conversion of garbage to Energy as a method of propulsion.
1 part Anti-Matter to 50-100 parts garbage, through a magnetic annihilation chamber/nozzle has always worked for me.

Sounds like a good idea for recycling as well IMO.

Answering the question about oxygen. It is pretty well established that on or near the surface of the moon water exists in the form of ice. Oxygen can easily be extracted from water. The moon does spin, the rotational period just coincides with its orbital period around the earth. There are suggestion that an elevator could be located near one of the poles.https://en.wikipedia.org/wiki/Lunar_space_elevator

I can easily see how one would work on the equator but I don't see how it would work at the poles.

Which costs money. We wouldn't have to perform that procedure on earth.

But, on the moon, assuming a growing colony is the plan, there is no wind and weather to contend with as well as aircraft and the ever growing quantity of orbital debris. Also the strength necessary for the cable is much less than what is needed to build one here. Then there is always the possibility of a catastrophic failure which here on earth could kill thousands of people whereas on the moon a failure would be a financial disaster but the danger to people would be minimal.

This all assumes that a permanent base on the moon is being established without which it is a moot point.

We have to consider various factors but IMO earth would be a better and safer place to work out the concept.

The whole idea of building a space elevator is bring the cost of getting to space as cheap as possible (once the original cost is recovered). Building one on the moon where gravity is much less would have less benefit and it would not help reduce the cost on this planet at all. This isn't to say that putting one on the moon makes no sense it just seems earth would be the priority.

Agreed. We also have to bear in mind that the moon is subject to cosmic radiation as it lacks an atmosphere.

Uhhh ... get to the Moon, but then get from the Moon to some other place more easily in 2 hops than 1 direct hop from Earth to non-lunar destination?
