But that money wouldn't be going to Nasa. They will get rides on private rockets. And so if they are going to be spending many millions on getting there, Nasa should be charging much much more than 40k/night. A million/night would be more than reasonable imho given what tourists will already be spending to get there.
"These companies are likely to charge any private astronaut a similar "taxi fare" to what they intend to charge Nasa for its astronauts - close to $60m per flight."
