I'm not (too) ashamed to admit that I'm a bit of a gearhead, and not just in photography. I would also like to think that I'm a photographer, but some people may say that ain't the case. Ahh....
I think just about everybody would agree that the right thing to do with a camera is to take pictures with it.
I think just about everybody would also say that there isn't anything wrong with looking at a camera, and admiring it, without taking pictures.
Most of us on this forum live in free countries (hopefully someday all of us) and as such, as long as you aren't hurting anybody, then what's the big deal?
A lot of times the people who insist that collectors are jerks are people who can't, for one reason or another, get the things they want, and they blame the collectors. That may be fair, that may not be. I personally pine, lust and pray for a Leica. One of these days I'll be able to get one. Until then, I will be silently jealous of people who have them, and I will silently hold "collectors" in contempt, because they have something I don't have. I will do so silently though, because I know that it's only a product of my own inadequacy, and not rather something that the "collectors" are doing wrong. It's no big deal if somebody collects, shoots, or oggles. It's their camera!
On the other hand, most of us would agree that a Rembrandt or a Van Gogh belongs in a museum, where it is both reasonably assured of longevity, as well as public access. Few things make me sadder than having the world's greatest art being bought up by collectors, to stash away in their basement, never to see the light of day again.
But then, that's life I suppose.....I was almost heartbroken a few years ago when that Japanese billionare bought Van Gogh's Irises (or am I thinking of Starry Night?) for a monumental pile of cash...when the media asked him about it, he said that he would bury the painting with him when he dies. I think it's pretty normal for people to say that that's just about the worst thing to do with such a painting.
Cameras are different though, because there's always another one...so let the collectors have their way, and live your life the best you can, either way.
To the consternation of my wife, I like to keep some cameras on my bookshelves, so that I can look at them. Yes, I shoot them (I don't have the money to "collect") but I like looking at them when they're at rest.
To paraphraise Plato, a thing is its essence; a camera is not just a camera, but also an object of photography, and a tool to make photographs with. A hammer likewise is not just a hammer, in its essence, it is an object you can use to pound nails into wood, kill Cockroaches with, or even scratch your back. But, it is a hammer.
So to look at a camera is to see and understand its purpose; whether you are taking pictures or simply fondling your Leica MP, you're acting photographically, in response to a photographic object.
So perhaps there are logical legitimizations of both collecting and shooting, and perhaps both pasttimes are indeed largely the same thing.
Personally, I think my gear-headedness is somewhat logically founded...when I spend countless hours pining for a Leica, or a Linhof, or whatever, I don't just think about how cool the thing is, but rather I think about what I would do with it...this picture, or that picture, etc.
Likewise, my wife thinks it's ridiculous how much I know about fishing reels and rods; what she doesn't realize (boy, I am an addict) is that different equipment accomplishes different purposes, and does things differently according to quality, etc.
Or when I look at a '74 Dino driving by (rarely) I don't just think what a lovely car it is, but I imagine myself driving it in the hills of Eastern Oregon, swooping through dangerous curves at just a hair under stupid speed, the tires gripping the road like a monkey holds a banana.
Of course then there are some of us who think the same way when they see beautiful women walking down the street, so I think you guys understand. (I know what people would say if somebody simply "collected" women, although fondling would be much more congratulated.
