They’re literally doing capitalism. M - C - M’ is described in the first part of Capital. This is money operating as capital. Buy a commodity for M, then sell it for M’ that is greater than M. You have no interest in the use value of the commodity. The only thing that matters is it’s exchange value.
I've seen a similar thing with gun guys (since I occasionaly visit /k/ to pilfer gun pics, and end up feeling like a scavenger diving in a toxic waste dump). Constant whining about ammo shortages, people buying up rifles so they can price gouge, youtubers selling out, this or that company catering to the military and law enforcement markets instead of civilians... that's literally just the free market at work you morons, if you're gonna whine about that shit then I guess you have no option but to become a communist.
