As for the people who "don't have time", why in the world are you playing a role-playing fantasy game where battles can take over 30 minutes?
Oh really? it ruins the value of when you catch a shiny pokemon? then don't catch a shiny pokemon and the value wont get ruined. lets say that someones dream is to catch a shiny dialga, and they reset infront of it for years, and never get one, when they could have jus used AR instead. which one sounds smarter?
I don't have an Action Replay (I may get one for cloning), but I'm ok with the use of it for things other than hacking pokemon with perfect IVs (actually I'm ok with that too as long as you aren't trading with or battling me...it's your game), but something that bothers me is when people use "not having time" as an excuse for hacking stuff. It is very unlikely that if you have time to actually play the game and post on online forums like this, that you don't have enough time to make Action Replay not be a necessity. Just say you don't want to spend the time, rather than you don't have time.
Also, having 31 IVs pokemon and perfect natures across the board aren't requirements for putting together a decent team and battling online. It may put you at a disadvantage, but having perfect IVs and natures does not guarentee a win in pokemon at all.

Except for the fact that this scenario is highly farfetched (However you spell it)
AR to modify iv's is something i am totally against, even if they are legal. People spend time breeding for stuff to get the advantage only for someone to come along and take it away by creating something with perfect ivs because "they dont have time" and its "still legal"... totally unfair if you ask me.
Hacking wild blisseys for EV training is about the same as just hacking your EVs without EV training at all.
And "popping" blisseys is a hack, because they don't just pop up (at lv2) in the grass normally. You had to hack the game to get it to do that.
