If nobody ever tries to build things which are physically possible but are likely to be blocked by regulators, we will never learn what the true constraint is. Most people around us believe that economic growth slowed down to near standstill due to some physical/technological constraints rather than was regulated away. We need more people like Musk who expose the truth that the regulations and bureaucracy are the largest problem the West has been facing for the last 40 years.

  > a man that promised to build something cheaper and better

No such promise was made.

In fact, Musk explicitly went out of his way to say that he was not promising to do it himself.
