Just because you don't want them to be true, does not make them true, and you can't just dismiss them. In any system with scarce resources, some rationing mechanism must be at play. If it isn't price paid, it is something else like a lottery, who you're politically connected to, etc.
Sibling comment has it right. Valve is making a choice here. I think it's a better choice than raising the price personally. I detest scalpers with a burning hatred, but the way to combat that is to understand the economics behind why and how it works, not to ignore it and dismiss it with "the rich get richer"
Just because somebody disagrees with you doesn’t mean they don’t understand basic economics. You should be a little more charitable in your discussions.
If they were responding to this part:
> why would you work hard to create value for others in a system like that?
Then their answer of no makes no sense, so I don't see a way to be much more charitable
