Then you've chosen my second choice, living with it. Advocating for improvement is exercising your options to participate in the conversation, even if your participation only amounts to acknowledging our collective lack of knowledge.
Isn't it great that reasonable people can discuss things that are complicated? Think of how many intractable problems have been solved because people were too stupid not to know they were insolvable?
Expertise is easy -- you can rent it when you need it. Highly-effective teams working tough problems are not easy. It's perfectly legitimate to say something along the lines of "hey, we're sadly lacking in knowledge here, and here are the steps we should take to improve things" but that is a just another form of participation.
