I think the life support problem on Mars is a supply/demand problem. We haven't been able to make it yet, so why worry about developing life support systems? The initial proposals I have seen is to send robotic missions first to prove out the land/launch capability. Even if it's not SpaceX, someone else will probably follow this pattern.
