Yeah, low volume space tourism is fine. Bezos and such are funding quite a bit.

What I was getting at is the meme that “mass” space flight (much less interplanetary colonization) is in any way practical. It is not. It will not be, at least not until civilization is more along the lines of Orion’s Arm or similar sci-fi. KSP is a fantastic illustration of that, as (even with a much smaller planet than Earth) one pays for every ounce that has to move in space.
