I disagree that it's +EV. It increases the luck element in the game substantially.
The biggest advantage the expert player has is the ability to outplay his opponents post-flop, which often means folding when they would've called. Dumping more money in pre-flop (without any chance of eliminating players) before the major luck factor (the flop) has hit, you are reducing you post-flop edge significantly.
And if you think you can make up the post-flop loss with pre-flop tightness, all that means is that you'll be able to play fewer hands, which is more boring AND less profitable.
To illustrate by using an extreme: Imagine playing a 50/100 game with a 1000 ante. How much skill is there in that game? It'd be completely unplayable from a +EV point of view.
