I'm afraid I'd have to agree with you. The argument that "it's already cheap enough" is valid and Apple will also argue that they made iLife an a-la-carte purchase. Let's face it, not everyone needs/wants all three software solutions. Personally, I prefer using Keynote and Pages only and using Excel for my spreadsheet needs.
Personally, Keynote is all I really use - but I got the bundle for real cheap so I went with it.
it'd be nice if they brought out a viable competitor* for Excel and Word but I doubt that all happen.
