Scalpers are essentially making use of a market failure - namely Sony/Nvidia/AMD/etc. failing to increase the prices of their products even though the supply can't meet the demand (due to a chip shortage). The fact of the matter is that there isn't enough products at MSRP for everyone who'd like one, even if you eliminated all the scalpers who buy up the products at MSRP. So either you discriminate by price (which scalpers do) or by time/luck (hitting F5 at the right time on Amazon, checking Twitter bots all day). I don't understand why the latter is more virtuous than the former. Frankly, when it comes to luxury products I prefer an auction over a lottery.

Scalpers buy products at MSRP, and redistribute it to those who are willing to pay more for them, thereby providing value as the recipient doesn't have to waste their time following Twitter bots day and night. They don't affect supply because they're obviously incentivized to resell. They do affect demand as the demand for a $1500 RTX 3080 is lower than for a $800 3080 but really, that's how price discovery works. If your price is such that the product is out of stock all the time, you've priced it too low.
If you hate scalpers, you should beg for the manufacturers to raise the console and GPU prices to their actual market value (they probably don't do it for brand perception reasons or otherwise). Currently, the products are simply priced too low.
edit: This is neither clickbait nor cringe lol. I've responded to literally everyone in good faith. I'm just correct and I'm sorry it hurt your feelings. By the end of this thread, 40-50% of you guys will be pro-scalping, so keep coping mods.
