Seems to me that once you've solved the problem, applying it across a variety of unrelated products is an easy thing to do, with the advantage that your solution is already proven, has gained some traction in another sector and is not something new and untried. It's one of those things where the first one to win is likely to win big (unless they fuck it up along the way somehow.) Not sure how your comment on PoW applies, though (despite agreeing with you.) Plenty of the solutions in developments are using PoS/other/hybrid consensus mechanisms.
