Remember when people actually used their Playstation and Sega Saturn discs in the 90's? Retro gaming used to be a cheap hobby because people used the games and consoles for their intended purposes. Now everything is overpriced and it's impossible to find anything decent at thrift stores or garage sales anymore. Neckbeard resellers now clean out any retro or thrift stores if they can make at least $1 reselling old junk when in the past it was considered shameful to be a greedy bastard who hoarded everything, especially if the profit margins were so slim. Many collectors are also annoying spergs who demand that 20-30 year old games are somehow still in perfect condition and will give you bad feedback or demand partial refunds if there's a tiny little scratch or fingerprint on the disc or case even though it was mentioned in the description. There seems to be an overlap with consooming and people with autism, hoarding, obsessive compulsive disorder, and just plain greedy assholes who never grew up.
Some people say that you shouldn't worry about it because they're only harming themselves, but the truth is like I've mentioned is that hoarding and consooming often affects other people that are forced to come into contact with them in a negative way too.
