You spin up your station. You're not limited to whatever accidental value holds on the planetary surface. This was all studied back in the 1970s and 80s, and free-space development makes way more sense: http://www.nss.org/settlement/ColoniesInSpace/

And this adds a whole new set of engineering challenges and project risk. Nobody's spun up anything bigger than a rocket stage to date.

Of course space settlement is many steps away; so is a permanent settlement on Mars. You need to analyze the payoffs and costs and intermediates and uncertainties for each.
