Good question.
As a guitar player, I can tell you that you are right. I think there could be a couple of reasons for this.
1 - It takes a lot of work to build say, a Les Paul. It takes an awful lot of fine craftsmanship to make one play like a Stradivarious and look like a gem. From cutting the solid mahogany slab of wood into the shape of a Les Paul, to carving and shaping the top, to the intricate paint job, to the electronics, creating the perfect neck shape, the binding, the inlays etc. etc.
2 - Even non guitar playing people understand that sound really matters in guitar playing. For instance, a semi-hollow body guitar will sound different than a solid body and a solid body will sound different than full hollow body, single coils will sound different than humbucking pick-ups, a Fender will sound very different than a Gibson etc. and the differences in all of these things are dramatic. Most famous guitarists have there own sound, that is immediately recognizable to most fans and they know exactly what guitar there guy is using to get it.
I don't think its the same with drums. I think there is less work, or should I say craftsmanship, to building drums than guitars. Correct me if I'm wrong. Also, my guess is a luthier makes more money than the guy that builds the drums as well? Does the drum builder even have a craft name? Are drums hand-built?
You can almost get any drum to sound and play reasonably well, which is not so for guitars. Also, I don't think that most people have any idea that drums can have different sounds. Or that they need tuning. I'm not sure a fan could pick-up whether or not there favorite drummer is playing a Gretsch or a Ludwig. I think people think drums are just drums and some are prettier than others!;)
Now, I hope I didn't make anyone mad with my views, that was not my intent at all, but as a guitar player, and a newbie to drumming, that's the way I see it.
