Earlier quoted context omitted.
I don't think launching sports cars into orbit is inherently any more wasteful than say the development of the Deep Blue chess computer. It may have been a vanity project, but the ultimate goal was to test a proof of concept.
I didn't say it was wasteful or make any judgments about it. It's just a fact that a level of lifestyle that allows a person to launch his personal sports car into space has been achieved.
While he and many others could buy personal space launches, that launch is not a demonstration of such. He wasn't paying for it, and it wasn't for him.
