And what of spending money on stuff just because you enjoy collecting? From my limited knowledge, it seems like most buyers are motivated by that to at least some extent.
If it's something you enjoy collecting on its merit, go ahead. If it's something you enjoy collecting because it's rare, that speaks to a subtly unhealthy motivation of wanting to have something that other people don't have. Put it this way: if other people doing well in your hobby makes you sad rather than happy, it's not a good hobby.
The issue with trying to pump prices is that it creates a speculative market that drives most buyers out of the market. We see a similar situation in the PS5 space where demand still outstrips supply and scalpers are wildly profitable.
