As a technical person you are thinking about the problem. That's why I love being technical.
In a power structure it is more complicated. "Why can't a rocket be reused?" Well, Elon Musk is a technical person with power so not only can it happen, everyone will get behind it.
On the other hand, why should my car HAVE to be internet connected if I don't want it? (or have a proper dashboard in front of me instead of the side?)
Consider these: why cant a rocket be reused? Why cant it just land? Why cant we just invent a new material?
"What if we just...?" Can be absurd, but it can be worth confirming that.
