It does, but a supersonic personal jet is a much bigger feat of engineering than a rocket that lands. Most people don't appreciate that. We had landing rockets in the 80's, but Boom was trying to do several things that are completely new. SpaceX's real technology is about launching the rockets cheaply, not re-using them (which is only part of the problem).
And SpaceX started with engineers who knew a lot about the domain of the actual problem (rocket engines). Boom has never designed an engine.
Starlink satellites are a great example of SpaceX solving engineering problems that an incumbent couldn't, but SpaceX was a pretty large company at the time the effort started.
