I think it depends on the game, really. There are a lot of games where a split-screen feature works well, the prominent sticking out in my mind being racing games. Some 3rd-person shooters may work, too, if the game itself is not too visually busy... Gears of War is a prime example of why I'm on the fence here - it works, but it detracts heavily from the immersion. Then again, local multiplayer works astonishingly well in Army of Two, a game where fun is instantly quadrupled by playing split-screen co-op with a buddy.
Also, local multiplayer is an absolute must in any 2D/2.5D sidescrollers and platformers, such as 'Splosion Man or Super Smash Bros.
In most of these cases (racing games in particular), if a developer decides against local multiplayer, then yes, I agree with you, OP.
In some games, however, I am decidedly against split-screen, because the game itself is too visually busy and I really don't want to share my screen with someone because I want to marvel at what's going on around me. This is where online co-op comes in handy.
It may be a bad example because it hasn't actually been released yet, but take a look at how Transformers: War for Cybertron deals with this issue - the way they implemented drop-in/drop-out online co-op looks extremely convincing to me, and the reason they did it (according to them, so this must be taken with a pinch of salt) was that there was too much going on on-screen for them to split it.
Then again, money is always a factor, so what do I know.
