Got it, so when say a private individual or lab decides that the cost of continuing a line of research or development exceeds the predicted benefit/profit and cancels it, you think that's a missed opportunity regardless of the context? Every invention everywhere should be shipped and never rolled back, no matter if it is profitable (on any time horizon) because eventually there's a chance it could return social benefits?
