While the authorities do usually ask for the public's opinions on contentious issues, the end decision is made by so-called experts. There are a lot of politicians who are lobbying against Bitcoin currently. They could easily influence the decision makers.
The decision is never made by experts, the decisions are taken by politicians because that is their job they cannot delegate to anyone, that is why they got elected, at best they will consult experts about the topic and then form their own opinion and based on it take a decision, but we know that it does not work like that since politicians are only looking at ways to benefit themselves.
