I wonder if the write thought this through before he went to bemoan the idea that the rich will be the ones who can afford it. I'm all for the rich to spend their money on this and more so. If you look back in aviation history, those first long distance commercial flights were not cheap comparative to that era. Only the very rich could afford to go fly down to the Keys or from NYC to LA, the average person had to take a train, bus or if it was overseas travels, passenger ship. Aviation travels caught on with the rich because it saved them time, and time is either money (business trips) or pleasure while the airlines grew from providing this service. Jet airplane travel was not cheap, again, only the rich could afford it. It was a status symbol to be a "Jet Setter", so more and more paid the high ticket costs which grew the commercial travel industry on the backs of the rich. Today, it's often far cheaper to buy a ticket in advance on Spirit Airlines then it is travel by car, that is only happening because it's a mature market that was funded by the thrill seeking rich some 80 years ago.
This is the same way it has to happen for space travel so that the average person can afford to go for a sub-orbital and hopefully one day, a orbital trip. Rich have to be there to financially fund development and refinement of space travel, government will just FUBAR it up like they did the human space program over the past three decades. Toast the rich as they begin this phase of human space travel, they are funding it, and they are literally putting their lives on the line to make the system more economical and safer for us common folk in the future.
