Good point about billions of cars having more impact than a few fuel-hoggy rocket launches.
I just hope that space-tourism doesn't catch on, because while you're correct that overproducing rockets to make them slightly more efficient does not make you more environmentally friendly, burning 25,000 gallons for a couple of recreational hours off the planet just because you have way too much money does make you an environmental monster.
