Playing with tool use is adaptive for humans. Our genotype is to blame for buying neat gear, travelling to exotic locations, and learning composition. To the beast at the core photographs don't matter because, unlike a better plow or better weapon, nice photos won't improve our mating success. At least, it's never worked for me. Come to think of it, buying expensive kit would be selected against. Our significant others divorce us when they see the bills and that restricts opportunities for gene transmission.
More seriously pleasure, as used in this thread, is undefined (real definitions of pleasure are depressing). Taking pleasure in a camera can mean anything. Cheerfully imprecise, I can say that I enjoy my fancy kit and learning to use it. I don't much care about the photos it produces, except as they reflect a progression in mastering the craft. Good thing too, because pros would regard my photos as pretty poor. What, me worry? No, and I am just saying that it doesn't matter whether we use one camera or another. We are wired so that learning to use tools is the important thing. I think that is the point posters often make about camera selection. Don't worry. Have fun.
