Why can't we have any other organization to which we delegate our power, but which then does exactly what we want it to do?
Because with the power comes an opinion on how to best wield it — maybe entirely for the good of the community, but often not limited by that. People why strive to be in control most often have their own axe to grind, too.
But a larger problem is the "they want". "They" are many people, and their opinions on a particular topic are "mostly aligned" at best. This is not a single opinion or want. This is why any collective action of this sort can be "mostly satisfactory" for the participants at best, and often quite disliked by some minor fraction of them.
