On one side, this is not possible on a practical level, because of the sheer amount of work and knowledge which is necessary to answer particular questions on a meaningful level. On the other side, political parties are a bit what you demand, just on a more abstract level. At least in Germany, we choose them for their specific answers to our questions (or should do it that way), and then hope that they implement them. Though, in reality, politic is complicated and full of compromising and accepting reality. So it's not always possible or good to actually do what the crowd demands. While it's true that most countries should use more democratic power from their citizen, the unsolved problem is how that can be implemented in a good way which would not harm the country long term. See Brexit for a case where this completely backfired. Or the ending of atomic power in Germany, which now backfires because the country can't stop coal mining.
