I guess that depends on who gets to decide value and in what manner.
Settled scientific facts are not the same as politics and policy. They can be useful in determining policy, but are not a default policy. It also depends on how those facts get linked together. You need to question the n-order impacts to devise good policy.
"If there is a belief among some that settled scientific questions are a matter of non-expert public debate, then that needs to be corrected."
Policy should be debated by the people. You need an informed citizenry for democracy to function.
Sure, we can publicly shame people for just about anything (1st Ammendment). What is acceptable depends on what the group or society decides. For example, should we fat shame people to reduce healthcare costs on aggregate?
We also need to weigh societal benefit of shaming against any societal detriment like a reduction in civility.
