Really? That makes no sense. Why would online play matter in the least when talking about a non mobile platform? Do you ever even take your console offline?
I'd much rather be online (my PC is online 24/7 anyway) than suffer hacking and duping issues.
I just prefer to fully own my games and be able to play them on my own terms when and where I want.
And I don't care if somebody I don't know wants to hack in their own game, it doesn't affect me at all. Let them cheat, they're only ruining the game for themselves.
