Which is probably because they don't want to show it live. If they wanted to, I'm sure they could find a way to get enough bandwidth to it.
Their PR is very well-run, and not only will they not show a live video for something that they aren't sure is going to go right, they'll also have a plausible technical excuse for why they can't do it.
Not that I have anything against running your PR well, just admiring it.
I don't buy it. I'm sure Musk (and many others) would like nothing more than to watch the event live. Just having the stream doesn't mean they'd have to show it to anybody. It could be kept private. The fact that they don't have a stream at all means it must be pretty hard. Certainly it can be solved, but it's hard or expensive enough that other things take priority.
(Note that the seeming ease with which they send live video back from the rocket during the launch tells us nothing. It's relatively easy to receive high-bandwidth data from a rocket above the horizon to a tracking station with a big dish that it can point at the rocket.)
In the early launches, whenever something went wrong the stream would be cut off instantly --- sometimes they'd even leave the connection open but just stop sending frames, which made my video player very sad.
I sympathise: they don't want to be associated with failure. But on the other hand, there were an awful lot of people, including me, who would have been utterly fascinated to see a first-hand view of the failure modes.
