a/Space launch ~10B/yearGlobal Space launch revenue is less 10B/year.Will probably not grow significantly.Low risk for Spacex, limited grow.
You over-estimated some of the LEO and free-return tourist revenue by almost an order of magnitude and under-estimated government projects by an order of magnitude.Flights to the lunar surface and Martian surface as part of "tourism."80,000 people to Mars every year (so more per synod) at $200k/ticket is only $16 billion, by the way. Their low Mars settlement ticket prices will depend on sharing infrastructure with higher revenue projects.
g/ How about de-orbiting problematic space junk using re-usable rockets on some kind of contract from spacefaring nations? There's something like 20 thousand pieces of junk in various orbit families.

Growth rate has not exceeded about 4%. It would take about 40 years at 100% market share to get to $10B

And many other problems. The same issue covers many of them however, and that is is "someone else's problem" I.E. there's absolutely no money or incentive (other than self preservation perhaps?) for anyone to do anything about it. I have never seen any indication that there was a customer out there putting a bounty, or any other money on the line for de-orbiting space junk.Yes, space junk absolutely should be addressed, but it either has to be so cheap that it can be done with no profit, or find some way to "industrialize" the problem. Make every launch pay a "disposal tax" that goes into a fund, and if you manage to de-orbit some junk, you get paid per kilo out of the fund? Just the first thing to come into my head, please don't take it too seriously.

Dragon is much lighter than second stage and payload...So this would be a much longer ride. Normally first stage by itself tops 160 miles so without a second stage the dragon could go even higher.They say the first stage without landing legs and fuel reserve could go orbital by itself.Fuel cost about $200k, but lots of other support required, including range which might well cost something.
