Earlier quoted context omitted.
The counter argument, is that relying on benevolent government to ensure a desired outcome is just as naive. In both cases, the holders of power are people . You're just trading one person for another.
You're trading one person who has no accountability to you in particular or the populace in general with a group of people who have at least some meaningful accountability. That's not an even trade.
Democracy, as has been said, is the worst political system, except for all the others, but let's not lie to ourselves and ignore that in some contexts it is, in fact, strictly worse. The classic example, of course, is an army led by direct democracy. When a thing must get done, and damn the consequences, then there really is no substitute for autocracy. It's just unfortunate that the people who eventually end up as autocrats are rarely there to benefit the community. Building systems of accountability and responsibility through culture and non-systemic factors may better this (see, for example, the 85 terms of Roman dictators who did not try to seize any more power than they had been given by the Senate and in fact often returned their powers before their term was over), but culture-crafting to accomplish that is unfortunately beyond us at the moment.
