Cause he can't use armor on his overhead bop to take a turn, right? That never happens? Ever?
Not only that,but not every move that has armor also has to launch. Taking 21% and getting the opponent off of you with db3 isn't bad for a "get off me" move.
Also, a 14 frame move isn't useless at all. After a d1 on hit, you can either d1 again if you think they'll try to low profile, or use standing 3. Once you condition them, there's no reason why you can't use 2,2. In fact, 2,2 can actually armor break some moves on wake up. So then you can do 2,2 and check with d1, 2,2 into bop of they're cornered and you want the extra frames, or do 2,2 into the safe low option. It's a knockdown and from there you can try to armor break, bait a wake up, etc.
You can't just read the in-game frame data and immediately write off a move. Everything has a use and it's the player's job to incorporate it all.
