I've never purchased a pipe with the intention to never smoke it, but I do understand why people would buy a pipe as they would an art piece and never smoke it. I have taken months to find the right occasion and mood to smoke a new pipe, but I also do this with music. I'm very picky like that. I've also experienced a short moment of "guilt" over smoking certain pipes, as I question whether I should be the first to smoke it. That usually happens with new/old stock and thinking, "It existed this long without a smoking, so why now?" That notion never lasts, though. It merely occurs to me at some point in that first smoke.
BUT...I have dreaded smoking a new pipe when I purchased it from certain shops. I remember a shop out of Dallas that sent out catalogues (all black/white except their shop name in red). I can't remember their name right now. This was from the early-90s. I absolutely HATED how they cleaned and prepared the inner-bowl with some kind of proprietary black coating that was supposed to help the new smoker break it in. The taste of that stuff was often foul, and it was difficult to get it out of the pipe. I tried everything from using rubbing alcohol to rub it off. I tried various homemade pipe cures to mask that flavor. I even used sandpaper to try to sand it off. Nothing helped. I'm not sure who thought that stuff was a good idea...unless the idea was to cover any small burn-outs or pitting within the bowl. They did it to every pipe in the catalogue. After a handful of gorgeous, uniquely beautiful pipes, I stopped buying from them. It was saddening to see all those great pipes go through this preparation process. I still cringe when I read any store or estate website talking about "coating" the bowl. Sorry, but I DO NOT need any help breaking in my pipes. If you must, cut the old cake out, but leave the rest to the next smoker. Just my opinion. So, yeah, certain things being done to a pipe can strongly discourage me from smoking a pipe sooner than later.
