I like your argument. I once was anti-DH, but I came around during the time Ted Lilly was a Cub. I have never seen a man more disinterested in and afraid of an at-bat. Completely hopeless. The way I see it, there is not a pitcher on earth who will be held at an NL team's AAA farm club because, while he has three great pitches and stamina, he needs to work on his hitting or bunting. There is literally zero professional incentive to work on hitting for a pitcher at any level of development. On the flip side, no one is drafted as a DH. There's an expectation that a hitter can play a position, if poorly.

The arguments against the DH don't all appeal to tradition, but many do. I think competitive balance outweighs tradition. Beyond the micro level of day to day competition, the AL is at a permanent distinct competitive advantage in roster construction. They can offer older players or those with riskier health histories contracts more easily than an NL team because they can put the guy at DH.

The AL also can rest star players more frequently by slotting one at DH. This is fan-friendly, as it allows the audience to see the star player at. least hit a few times, rather than have a full day off or a PH opportunity. While this is a secondary issue, pro sports ultimately are a competition for the public's entertainment dollar.
