Is there any reasonable argument for using single-queue instead of multi-queue?

Age of Empires is a strategy game. The core mechanics are things like figuring out what your opponent is doing/planning and how to respond effectively, and executing your chosen strategy quickly. Thought precedes action, and the mechanical process between the two should be as streamlined as possible whilst still permitting the same level of possible flexibility and variety in play styles.

Age of Empires is not a button mashing game (at least, not at its core). The button-pressing aspect exists only as mechanism to deliver the strategy part of the game. Having the player press more buttons than necessary to perform a particular action is just button-pressing for the sake of button pressing. It isn't anything to do with strategic ability, it's basically one degree of separation from skinner box.

Therefore, having a mechanic that arbitrarily increases the complexity of the process is not only completely redundant, it is also the antithesis of the core principle behind strategy games, because it does not test a players ability to think quickly about which units to make and how to use them.

Single-queueing is, like the old system of villagers not harvesting resources after building a lumber camp, mill or mine, obsolete. It is an obstacle to the execution of a strategy that arises purely from a less helpful interface. It uses physical dexterity as a proxy for actual strategy. Not to say that physical dexterity has a place in AoE, but only insofar as it is an element of strategic thinking.

And yet, whenever I suggest enabling MQ in a Voobly lobby I'm called a noob and sometimes kicked (or they start the game without enabling, even though single-queueing is perfectly possible in a MQ game if you're more comfortable with it). Am I missing something here? Is there some major balance reason why MQ isn't used much on Voobly, or do Voobly players just really love their Skinner box?
