The closest we come to such a market is the patent market. But again here, it is virtually never the case that a company buys another company to actually implement its ideas. When was the last time you heard that a patent troll was bought in order to create a product? Never (or rarely).
Just because people don't get paid to glibly shoot their mouthes off (usually), doesn't mean there is no meaningful market for ideas.
Fundamentally, the ideas don't stand on their own. Their backed by a name institution that delivers results on the ideas.
Ideas are nice, but they're a dime a dozen.
Let me put it another way. The recommendations that a think tank comes up with isn't worth the paper it's printed on without the weeks/months of backup research that shows how the recommendations came about. That's what is being paid for, not the idea/recommendation.
Obviously, if you dont execute it then it becomes worthless.
Execution is in (almost) all cases the hard part of the equation.
You need both. One is the beginnging of the road, the other is the end. Many things happen in between. Let's not see the world so black and white please.
