Now, let's take a moment to appreciate the wide dynamic range of the humen eye. Sure, if you look at the sun you will damage your eyes but it's still possible to see the contours of the sun, it's not a big white blur in that part of the sky.

And with that same "tool", we are able to clearly detect stars at night.

If you have access to a camera with manual exposure settings, here's an experiment: Setup the exposure for a properly exposed, sun lit daytime photo.

Without touching the settings, take the camera outside at night, point it at the sky, and snap a photo. What do you think you'll capture?

The answer is: nothing. The stars are far too dim, compared to sunlight, to show up in the exposure at all. Most space photography is done in sunlight, of things that are sun lit. The cameras are set to properly exposed these sun lit things, and the lack of an atmosphere doesn't change the fact that the stars are just too dim to show up in the same exposure.

Elon isn't being completely honest or more likely is miscategorizing costs somewhere.

The NASA contract to develop F9 WAS 400M. That is a fact. The actual contract is more reputable than the words of a man known to exaggerate to absurd degree.
