can have a lean dev team and micro manage the player base.

That's certainly true, especially when there are monetary incentives to win at the game. I just don't think the above conditions are fun for gameplay and if I don't multiaccount, I'm going to be at a remarkable disadvantage on those that do and doing so means adding more precious time into the game to stay competitive. Granted there's no way of stopping multiaccounting even if you tell people not to, or use bots and etc at the current conditions.
