People act like with Falcon, they basically just get it off the drone ship, fill er up, and she is good to go again. There is a shitload of repairs/maintenance that has to be done to Falcon vehicles after every launch.

In space, you can't do that kind of repair/maintenance, you have to make sure the refueling is PERFECT. And this is with deep cryogenic propellants that very much like to boil off and cause pressure increases in the tanks they are contained.

That problem hasn't even been touched yet. In order to make Spaceship X happen, they need to figure one refueling out, which is difficult given the fact that Raptors run on cryogenic propellant that likes to boil off, then they need to figure out how to do 10 in a row without any issues, which is exponentially difficult.

And then there is the whole thing about everything working well for trip to Mars, and back.

And if there is a configuration that exists that can do all of that, its very unlikely that a company under the leadership of someone as Musk can ever figure this out.

For interplanetary travel, things need to start from either orbit or the moon. This has been known for quite some time.
