Phrase the question another way, why should we care about space?*

For our current space capability: There is nothing there we need. It is incredibly expensive to do anything there. The scientific experiments we can do there are of marginal interest.

For the longer term, it is hugely beyond our technological abilities, and the projected ones of the next hundred years assuming no singularity). Colonisation is a far off dream, whatever determines our survival as a species for the nex millennium will be decided on earth. And we are struggling with that right now.
