Tucker's analysis though, is dealing with the concepts of relative value and replacability, more than degree of difficulty (though he uses relative difficulty as a supporting reason for his argument).
He also makes the assumption at the beginning that run blocking is negigible, which is obviously a generalization, because you have to consider run blocking before you sign a player.
The point, as Tucker would make it, is that when we replace Casey Rabach, we shouldn't invest a considerable amount to do it unless we're getting a truly special player. He's saying "Don't give Jason Brown what the Rams did. That's spending stupid." (or Dock with Buffalo)
Likewise, spending the 13th pick on Mack is equally stupid if we don't think he's the best OLman available when we pick. It's just too easy to get a Center in the 3rd or 5th round to pass on a better lineman.
Tucker isn't saying "Rabach shouldn't be replaced because all centers are interchagable." He's just pointing out that if you spend a lot of money on a Center or LG (like Faneca), you're overestimating his effect on the entire line.
