I see that as blind optimism thinking it's just a matter of finding the right formula. Simply put the demand isn't there among the general population. Yes, the question is going to be how do we make money. The answer is going to be, with something other than Star Trek.
This isn't the 1990's anymore where a sci-fi show is state of the art and doesn't have that much competition on the dozen or so opposing channels. With 100's of channels available to most everyone, with fancy computer graphics getting more and more common, it's less neat and more mundane these days and really only sells to the hardcore audiences. Which isn't enough to sustain a series, nonetheless justify the costs of making one.
Enterprise's cancellation definitely factors into this. All those reasons factored into it failing and the problem has only gotten worse since then.
