Another major issue I see with Space Elevator besides the tether material is its throughput. What is the planned speed and the amount of payload it can deliver?
If we say that it can deliver a few tons of payload per day,
then the infrastructure costs (especially with alternative cheaper-than-currently methods) will be a very long term investment
and might not even pay for itself.

My understanding is moving 30 ton loads (probably gross earth weight) at 120 mph most of the trip, for a 30 to 45 minute trip each way. Say 720 gross tons per day for a guesstimate…
I’ve seen some suggestions of using simultaneous up-down transit to get both energy offset and mass maximization. The cable, also, can theoretically hold more that one car going up at a time.

But 120 mph takes 200 hours to get 24,000 miles up. AKA over 8 days!
