Why? There are enough Ma&Pa shops that already fill this niche, on top of eBay and FB Marketplace and whatever else. They stopped doing this before becuase they were losing money, why on Earth do they think it will be profitable for them now?
Are they professionally cleaning, repairing, refurbishing, and testing all their inventory? Highly doubt it. Whats the difference between them an a Ma&Pa shop aside from I would imagine higher prices? Why are specualtive investors ruining retro gaming for future generations? (I mean, I know the answer is obviously money, but its depressing and frustrating to see investors actively killing something you love. Not the first time and definitely not the last time though.)
