Jorge and PHW are both correct, certainly from a mechanics perspective.The larger question is why NASA continues to at times to reference what can be mutually exclusive requirements. Those being fly crews on American vehicles at the earliest possible time and the other being to create a new industry.
These statements applied when it fits the question only reinforces the central confusion and tends to lead to notions that downselect should happen now so all available resources can be focused appropriately. It does not help that potential providers are not advertising real external clients either (and Bigelow does not count, they have no customers also and likely would fly anything at this point).

Those requirements are only "mutually exclusive" if you make certain fundamental assumptions. But if you don't agree with those assumptions, (I don't) then they aren't mutually exclusive - rather they are requirements that work well together.

That last sentence is fundamentally untrue - Boeing is partnered with Space Adventures, which has sold every available Soyuz seat in the private astronaut market. Virgin Galactic is partnered with SNC (or at least they were).

And I note you made no attempt to place any context on the assumptions you believed I was making. b) You also gave zero insight or logic to prove my point wrong in even the slightest way or clarify why you believe these two objectives work in harmony seamlessly together.

Could the prospect of X-b37 play into deselection of DC? Kind of like when the judge tells the jury you're not allowed to consider some known matter of record.
1. I made no assumptions. And I note you made no attempt to place any context on the assumptions you believed I was making. You also gave zero insight or logic to prove my point wrong in even the slightest way or clarify why you believe these two objectives work in harmony seamlessly together.
2. It is not fundamentally untrue in the slightest. Any company can be "partnered" with anyone else and it is entirely possible no products are ever delivered or sold. Again with this statement of yours you actually do not add any data for evaluation.
Regarding the tower question? Will SpaceX require a traditional style tower for entry and servicing of astronauts? I ask this because they tend to be a little more "out of the box" than NASA and the other players. I've seen the quick turn around videos they have for later supply & private launches and can't help thinking that they would prefer to just strap the astronauts in on the ground then roll out the missile and erected it. (It just seems more like their style) I image NASA is dead set against it with the same vigor from a citizen's point of view, as the little old ladies who were against Rock & Roll but that doesn't mean one is right and the other wrong rather one just has the power of authority on their side.
There is a set of criteria laid out in the CCiCap documents of how things would be judged.

They won't strap in astronauts before the stack is vertical and ready to go. As for what kind of tower, I seem to recall an interview where it was stated that a separate tower would be constructed for crew access. (sorry I don't remember the reference)All in all, constructing a tower for crew access should be one of the easiest and cheapest tasks compared to the other long poles of making a a human rated spacecraft. It doesn't have to be a massive structure.
I'm starting to think it may play out this way. Boeing or Sierra Nevada will get the manned NASA contract for ISS. SpaceX would continue cargo resupply for the longer term beyond this contract not only to ISS but to eventual NASA BEO destinations as well. SpaceX would eventually move forward with it's own manned plans to the Bigelow station or other LEO destinations. SpaceX will also move forward with their long duration DragonLab.
What i'm saying is that I see SpaceX in a long term NASA support role mainly doing cargo resupply to LEO and BEO destinations. SpaceX would still have a manned option but, eventually by it's own doing.
