Why is it "stupid" to put at least part of humanity in more than one basket? The fact that major technological developments are in the offing soon does not mean that these developments will be used necessarily for the good of the race or even lead to greater survivability. Having humans spread out a bit seems more sane. The cost of a space probram such as Zubrin advocates compares quite favorably to really futile endeavors such as the Iraq war and much of the "War on Terror".
I do agree though that O'Neill and/or asteroid based colonies make a lot of sense and are much more within our currently limited grasp.

Yes, if it was my billions that is one of the first things I would target. OK, maybe Mars is a relatively poor goal at this time.
