Don't discount the possibility that maybe the solution that seems so obvious to you has been considered by experts and upon deeper study found to have serious issues and maybe wouldn't work after all.
I always remember once hearing a podcast with a recurring segment called, "Why don't they just...?" where they took obvious solutions like these and asked experts why they didn't implement them. So often there were **really good reasons** not to implement the ideas.
These issues are more complicated than I think you're giving them credit for, especially once humans are involved.
