Easy, just attach a huge rocket to the bottom of the elevator, problem solved. Oh, use AI to design the rocket, make the ticketing system use block chain, and when you get to orbit, a robot remotely operated by a human on the ground (but prentends to be fully autonomous) takes a picture of you and generates an NFT of it that you can purchase for 35000 USD in the gift shop.

I'll be over here swimming in my money pool.
