Reply to comment by robertojh_200 in Starship greenlit for launch after static fire test by DevilsRefugee

The physics doesn't have anything to do with finances. Until some actual engineering is done, there is no projected cost for this. There is no prototype design, or even a realistic concept design.

You don't know how often parts are going to need to be replaced, or how much it will cost to build initially, you don't even know what parts are going into it!

With so many unknowns, you seem quite certain in your criticism.

Their criticism is exactly that: there are so many unknowns that a comparison is useless.

The only thing I'm certain of is that you can't be certain of the costs enough to be comparative.

With so many unknowns, how on earth can you say "damn, starship is cost competitive with space elevators"?
