What a very interesting topic! I’m not so certain that it’s always the marketers that give meaning to material objects, but rather the possessors. Of course marketers need to give some initial reason for people to buy them, but it is those people who have bought them who must continue to keep them alive by investing and reinvesting them with meaning, which I find a fascinating process. If the goods have been gifted or if they have been bought for oneself, there is likely very different meanings.

As to whether there are any meanings that are implausible to invest in material goods? I think that there is probably no limit to people’s ability to imagine meaning in objects. I could be wrong, though.
