The US army is currently a Mercenary army because it is a high paying army that isn't defending its nation.
I think there is a difference between a voluntary army, and a mercenary group. There is a lot of "honor" (whether right or wrong or good or bad it exists) in being part of an Army, or in this part of the US Army. That is something that doesn't exist (or maybe not not as much of a degree) in the Mercenary world. Even if you are opposed to war, there is a level of respect you will give a soldier who says "I served in the Iraqi War as a/an ____" that you will not give to the mercenary who says
"I was contracted out by the USA through a private security firm to operate in Iraq"
In the army your job is to fight for your country. You will go to war if the presdient says you will. When you aren't in war, you are not "looking" for war. Mercenaries always have their "skills" for sale to the highest bidder, fight for potentiall many countries, and can choose to turn on a "call to war" if they wish.
I understand the comparison you are making (especially since I agree that our army isn't doing much "defending" right now) but I still beleive it is flawed because of the basic fundamental differences between a volunteer army and a mercenary group. It is a thin fine line that seperates it, but it is an important line nonetheless.
As for why not mercenary armies? Ask Rome that

OR just ask any empire in history that ended up resorting to using Mercs and their "experiences" with it
