If it isn't because the science supports it, why is that important? Countries do weird things for the wrong reasons all the time. The Swedish government says the sale and consumption of MSG is "unwise" because it "might be bad", even though there is absolutely no scientific support for it. I'm sure you could find many, many examples of similar problems in practice and it does not take a whole lot of thinking to realise it might impact other areas as well.

I mean its not like science could ever be politically biased /s

Politics.
