We might succeed in ignoring this doubt for a while—keep everyone so busy doing what it takes to build the ships to get us out there.

Problem is (follow me closely here, the science is pretty complicated), if I cut a hole in the Hab, the air won't stay inside anymore.
Humanity is like someone whose outstretched arms are reaching for the stars but whose feet are mired in the mud.
