It DOES matter. :)

Everything they're doing, and are planning on doing, has already been done.
So landing a rocket after launch to re-use that rocket has already been done? Going to be interesting when they are the first to do so but it's already been done. I'd love to hear how you reason that.
Doing things in a more efficient, cheaper manner means innovating new ways of development, testing, and building. More 'affordable' ventures into space can lead to an array of improvements. More research satellites being sent into space, as an example, because instead of costing $12 million to ship into space it costs $4 million [0].
I'm sorry you don't see the value in such things, but rest assured it is there.

And how about Tesla?
How about building inflatable space stations? https://en.wikipedia.org/wiki/Bigelow_Commercial_Space_Stati...
Or mining asteroids?

For my money, either of those is more "visionary" than "a rocket booster that costs somewhat less than previous rocket boosters".
Now granted, they're both a lot less practical, and it's true that making things cheaper is often a crucial first step towards making them better.
It's no different than when Rockwell/North American built the Space Shuttle.
The biggest problem is that his ideas are just so boring and uninspiring. How about a new idea for a change? (Hyperloop isn't more exciting than High-Speed rail)
Being known for someone that "did something for slightly cheaper" isn't exactly awe-inspiring. Sucks that millennials are stuck with him for inspiration.
I want to see new ideas from our tech innovators.
The Mars Curiosity lander is an amazing example.
