In order to "approve it" governments need to regulate it. This takes years to work out, and only now are they starting to take it seriously. The problem is, the more they dig into it, the more likely they are to ban it, rather than approve it.
Will need to wait what my country decides on as they are still reviving if needs to banned or regulated. It seems that till now things are not so positive that it may be accepted but hopes are high that they would not disappoint their citizens.
