Sometimes a solution — or a variety of different solutions — still have a significant pain point attached to them.
Just because of that, you can't derive with absolute certainty that there's "a better solution". It might just be the nature of the problem has no solutions that everyone "likes".
With something like climate change, issue is that the pain point for the problem is time deferred. An obvious comparison would be to lead in gasoline, cookware and paint: The problems that it caused took many years to surface. Getting rid of it was both expensive and required new solutions. Thankfully, we got out ahead of that problem... I'm curious if in the current political climate that would be possible.
