Also, your question sort of implicitly requires ignoring all the attempts to do "something like what Bezos did" that failed. A bunch of resources went into those efforts that came to nothing. This is not a zero cost to society. There was always going to be someone who succeeded at this, so noting that Bezos did so is relatively information free. The bigger question is whether the way this happened - let a bunch of money be thrown against the wall and see what sticks - is really the best we can do as a society and as an economy.
