>Scalpers buy up GPUs. There is less supply. That creates a problem.
Those GPUs are then sold immediately to real users. Scalpers do not increase demand.
Scalpers provide a service. They have automation or a way to buy stock fast at MSRP or closer to MSRP. Then they sell it to people who are willing to pay more in order to have the product now or avoid spending time to search for stock.
Scalpers cannot exist unless demand is greater than supply.
We are going to have to agree to disagree on this one. In the second link, it is in reference to tickets. At the end of the day, tickets are all the same. If you can't get the front row of the show, you'll accept something back a bit... because you want to see the show.
GPUs are different. Miners want specific brands and models and won't / can't accept anything else.
Scalpers are a symptom of the supply/demand problem. Not a cause.
