There's no chance of a colony of any kind. The bare minimum requirement would be to end dependence on shipping critical materials from Earth, and good luck with making that happen in the next century.
I'm not following. Are you saying that a colony by definition has to be self-sustaining? Why?
At this stage of globalization, what part of Earth is self-sustaining? How certain are you that if the US was suddenly blocked from importing any goods that it would not descend into chaos?
I'm not saying it has to be by definition, but the costs and complications in regularly transporting oxygen, water, food and everything else in cargo ships from Earth simply makes such a colony unrealistic even for a very small number of permanent settlers.
