best hope?

SpaceX hopes that Starship will cost $200k per launch and that they'll be able to offer point-to-point transport on earth under an hour for a cost of business class airline ticket. You'll go to space as a side effect.

Given that cost structure, eventually they should be able to offer a trip around the moon for tens of thousands of dollars.

Point to point transport is bs... there are so so many problems with that idea. I don't get why spacex even brought up somthing so dumb.
