One analogy I really dislike is, "Saying you must have a really nice camera is like telling a carpenter they must have a nice hammer."
I think the camera has much more influence on the final product than a hammer does so it's not a fair comparison. Unfortunately, I don't have a better analogy to replace it.
Let's not get into the argument whether it's the camera or the photographer, just come up with a good analogy.
Fill in the blank: "Saying you must have a nice camera is like saying _______________"
Put some serious thought into this and stay away from the common ones like "a chef must have good pots and pans" or "an author must have a great pencil" etc.
Lets see what you all can come up with.
