Moonwalker, all you're talking is "transportation". While the early stages of anything can in some cases be called indeed "exploration", after a while, they become "routine" and stop being that.
But putting a man on Mars is exploration. In order to do that, we need to learn ways to live on an extra-terrestrial body, and the Moon is a good candidate.
Going to the Moon and living there for 10-15 years is a step which cannot be avoided on the quest for putting man on Mars.
THAT is exploration!
Nobody claimed that STS is exploration so it's a waste of time arguing about this. It's also a waste of time arguing about the semantics of transportation vs. exploration, although it seems that you're freely swapping the two to match the argument.
For this purpose, here is the definition of exploration as it appears in
www.dictionary.net:
"The act of exploring, penetrating, or ranging over for purposes of discovery, especially of geographical discovery; examination; as, the exploration of unknown countries"
So forget SpaceX doing any exploration for the time being.
SpaceX may know how to build LEO platforms, but none of them has been certified for manned LEO yet. That puts it right with Vostok and Gemini, but definitely not with Apollo or with what is necessary for reaching the Moon or Mars.
Oh, and one last thing: manned space exploration does not mean only "building the transportation to get there". It also means training the crew, building and maintaing the right logistics, planning, etc. etc. It means having the right multi-disciplinary staff and the right multi-disciplinary experience Even if SpaceX knew how to do that (which it doesn't), it definitely doesn't have the resources for that.
So whether you like it or not, NASA is the only body which has the means and potential to do true manned space exploration. Now what it needs is somebody to put it back on its original track and exploration goals, clean of irrelevant politics (become the State Department with its "Muslim world outreach"), irrelevant goals (becoming NOAA with its "hurricane research" program), and of irrelevant politicians (too many to name here).
