Leaving aside the secondary markets for a moment---which yes, I agree with you on---do you feel ripped off buying video games online? They are, after all, just really large files.
I feel ripped off when buying a video game online costs more than buying the same game in a physical shop yes, or when a movie on a streaming service costs more than the same movie on disc.
I don't buy enough video games to really answer that - usually I buy a couple of games a year during Steam sales and that's about it. I usually buy a couple of books a month (print and ebooks).
