A very sound argument can be made that giving NASA a more centralized
role is largely what got us into the current situation. We need to set
private enterprise free and get rid of some disasterous policies such as
cost-plus bidding and putting all our boost eggs in one basket (which we
partially rescinded earlier in the 90s). It will help to kick out those
aspects of the Space Treaty that make private enterprise in space
extremely problematic legally and that make it difficult to do anything
compliant with the ok of an international committee.
But, a bit BUT, it is not clear that manned presence in space is the
best idea for many of our immediate space goals. It is probably much
more economically viable to expand space robotics to increase space,
lunar, and eventually Martian infrastructure to the point where real
wealth is being generated in sapce and an increased human presence is
both needed and better supported. Sending humans for every or even most
steps is grossly wasteful. It is one of the problems with having put
almost all our eggs into the Space Shuttle basket for so long.

A major colonization of Mars and the attendant terraforming is first of
all not a short-term project and second of all would take the entire GDP
of earth for many years if we did it on the scale you seem to wish.
That is what I mean by lack of financing. I think you greatly
understimate the cost using current means.
More than one expedition per 10 years is not going to make Mars a backup
for Earth anytime within the century. Mars as a preserver for our
species in less time than that, without drastically improved means, is
a pipe-dream. Do the math.
