Space-X are only delivering cargo to low earth orbit (a great achievement don't get me wrong) but perhaps your right the future of space travel will be dominated by private corps (I hope not). They have some way to go before they can land multi-ton habitats on Mars and life support systems when NASA itself only managed to land a 1 ton rover (curiosity) on Mars which was at the limit of their technological know how.
