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.Its still the politician will that will be follow here. A lot of them are anti-bitcoin, so for me it will be a uphill climb before they will approved or even legalized it in their country. Maybe even the so called expert consultant is not expert all. Politicians have already made up their mind on it. Bitcoin is illegal for them. And of course it will not benefit them as you pointed out which makes sense for them to go against it.
