Quoted from Animal:flippers for profit are a BIG part of the problem.
What you're really railing against is capitalism on a small scale. It's not a new complaint and it's still valid for people who actually want to buy AND USE the thing. Economists call it rent seeking behavior - https://corporatefinanceinstitute.com/resources/knowledge/economics/rent-seeking/
It's been happening with concert tickets (and other entertainment) for decades. Larger scale flippers used to hire people to stand in line at the box office.
The new hot toy at every holiday season.
The housing market- even worse there because in some cases the "flipper" is a corporate entity that just rents the place out and a real homeowner is 'permanently' priced out of the market.
One might argue that in the US this is a feature, not a bug. Part of the price of freedom. It's certainly annoying if you're the one who wants the thing for your own personal enjoyment.
I think there is a conversation to be had about what's acceptable and what isn't. Personally I'd favor some restrictions on large scale flippers but as pointed out earlier it's really no different to the end user if the flipper sells it to them at a 50% mark-up or the manufacturer raises the price to that level themselves. And the practicality of defining "large scale" would also be a challenge.
