why not?
one stop of speed/dof against 4 stops of IS.
I think it's reasonable trade off and something worth thinking about. For most of the users f2 at 35mm is still thin enough in terms of DOF. If I had to choose...let me rephrase it...if I had the cash to choose between those two I think the EF35/2 IS USM would be in my pocket..and unlike the Sigma, it would most probably fit there....

It really depends. I love IS on my lenses that have it, but the wider you go, the more you get into diminishing returns. With good technique @35mm handholding a 1/50 shot should be trivial. And needless to say, IS has no effect on subject motion. If I'm doing portraits I want the faster lens, no contest. I'd be hesitant to take shots of people even at 1/50th, going slower just means I'm guaranteed to get blurry people.
Otherwise the main uses I can think of are slow shutter for creative effect and low light environmental (I'm sure there are more uses I'm not thinking of). And there's nothing wrong with using it for those things, although personally I'd just opt for the monopod. IS is convenient, but in terms of stills there's very little IS does that a monopod can't do better for less money.
ShadowBlade is pretty much correct, the ones that really benefit from IS in these types of lenses are the videographers.
