If there are a limited number of an in demand item, people prepared to spend more money will get them first, welcome to capitalism. We don’t all queue up as equals and wait our turn, that is not how our society allocates things! I’m waiting to buy a gpu and maybe a cpu, once there is one at the price I’m prepared to pay, I’ll buy it, I don’t care who they bought it from.
There is no evidence individual scalpers are capable of operating at a market manipulating scale, it would take an insane amount of capital to buy such a huge amount of stock. The fact many people are doing it individually is not a market manipulation.
Automating the purchasing process or using a computer to complete a check out process isn’t a crime! As long as they don’t hack into a system, dodge paying taxes on profits or steal the items, I see no issue whatsoever.
We can either pay more or wait until the people prepared to pay more get theirs, maybe its a good incentive to find a way to earn more money.
