I think we all agree we eventually want humans in space.
However, as I previously wrote, I believe there will be a lot more people traveling, perhaps living, on Mars in 100 years, if we use the "agile" method now.
We went to the moon over 40 years ago. It only took two accidents to really slow the process down. Now the US' plan for human space flight is to pay someone else.
You might be right about your "agile method" but I would bet on the other horse. How realistic is it, to take mined material back to earth for a profit? I can't think of any material even if prices for transport would see a landslide.
Also, I don't agree that Apollo was killed because of Mission # 1/13, if thats what you mean. Apollo was most of all stopped because it had done its purpose, showing the world that the US was superior to the UDSSR. Why exactly the few remaining missions, where killed puzzles me though.
