One thing is that many people in GOG are collectors, in which case it just seems a bad idea to get only a base game without official expansions, especially if you fear that later you locate a complete edition somewhere else anyway. If I e.g. wanted Syndicate and saw someone selling the original with the expansion on ebay for e.g. $10 or even more, I'd definitely go with that instead of getting it from GOG, just for completeness' sake. It is like pondering whether you should buy Kill Bill 1 Collector's Edition from some service knowing that if you'd later like to see also Kill Bill 2 (from some other service/retailer), you'd have to buy Kill Bill 1 again from the new service.
EDIT: Add to that also that many people buy here games that they already have as CD versions, but complete with the expansion packs. I'd love to buy e.g. Rainbow Six and Rogue Spear here just for the CD-less gameplay and guaranteed(?) compatibility with new systems, but it just seems pointless because the versions here are incomplete compared to what I already have.
Whether the expansion matters to the gameplay, depends. I feel that e.g. original Starcraft, Ultima 7, Diablo 2 and Alpha Centauri(or so I've heard) wouldn't just be the same at all without the expansion packs, even though you could argue that when they were first released without the expansions, they were already "complete" games.
Also, some expansion packs enhance even the base game. For example, the Age of Empires expansion (Rise of Rome, IIRC) added some much needed features to the base game, at least if you played the base campaigns through the expansion pack.
If the expansion pack is merely a collection of (fan made) extra missions which adds nothing else to the base game, or a DLC which grants a funny hat to your TeamFortress 2 character, then I probably couldn't care that much.
EDIT: Many already said basically the same thing, I guess.
