Artificial light isn't the best, but it can be made to resemble daylight; I don't see that as a show-stopper. If we can find some nice lava tubes that can be sealed and pressurized, it might make for some rather spacious dwellings. But yes, I expect the first Martians to effectively be mole people. I imagine living on Mars would be a lot like living in a place like Whittier Alaska [1] (a town where everyone lives in the same building). Not for everyone, but some people might like it.
