For that , it spends an hour or so getting to altitude at a less than earth shattering speed. And the current cost is $200K. So you wind up with a very expensive short range transport with a mediocre average speed. Lose, lose, lose. Let's be practical.$200K x nine, so $1.8M for a flight. Thus even worse. SS2 will never be used for such a thing, nor WK2. That is not to say there can't be a design that closes the business case (see for example Lindey and Penn in one of more AIAA papers) but not with this architecture.

I can't imagine anyone would think I was making a serious comparison between technologies separated by a hundred years. The Wright Flyer was the first successful privately-developed HTA aircraft.
Comparing Dragon to the 707 is equally absurd. Commericial private airliners existed for decades beforehand.
One of the big differences between air travel and space travel is, there was no huge government "air race" conducted in the 1850s from which the technology could develop.
Ultimately, the biggest difference between commercial manned air travel and commercial manned space travel is, there's nowhere to go yet.

When this happens what do you think will happen in this area. Everything depends on what a corporation/consortium or other group can make a profit from. IMHO there is next to no chance that pure tourism will make private access to LEO profitable. It will be a small fraction of the business model of whomever gets started first. My bet is on Platinum mining to be the first profitable enterprise in space. Whether it will be from asteroids or the moon will be determined by whichever is the most cost effective.
