Governance and responsibility among others are two of the problems involved in blockchain technology. Being used to centralization, people are somehow dependent to the leaders for decision making which is not the case when it comes to blockchain. All will be the decision maker when it comes to blockchain so there are times when we don't know what will be the outcome of something.
Responsibility is one of the problems as well because we like to find someone responsible for an act so that we will know to whom we can go in case we need something but when it comes to blockchain, no one has the single responsibility since the one involve are all responsible so you cannot pinpoint someone. Trust is not there that's why some are still doubtful when it comes to cryptocurrency being unregulated.
