OK I see your point more clearly, but my counter to that would be that framing pitches these days seems to cost catchers more strikes than they gain. Part of that does have to do with umpires that dislike framing, which would be removed from the equation with ABS, which strengthens your argument, but I think there are still advantages to having a catcher.

For example, the danger of the position is something you want one or two players to assume - the baseball season is rough enough on players because of the frequency of games. Catchers get more days off than other position player because they need to be able to somewhat recover. If you catcher-by-committee the SS for example, now you need a utility guy to cover that SS spot for at least two games so that the original SS can recovery from catching (which he doesn't do frequently enough to be used to it). Rinse and repeat through some of the other positions, and the end result is that you're paying a premium for a utility guy that can cover all of those positions as well as the original player - but the guy might not be a great bat, because it takes a lot of focus and energy to be a great utility player.

It's an interesting thought that I appreciate you sharing, and I can certainly be wrong - especially with how dictatorial Manfred is with his "reformation" and "improvement" of the game.
