Not sure if I disagree or not. Sorry if I'm seeming pedantic. I guess it's denial.

I don't think it's purely denial but uh, what's that term for when you project a series or umbrella of things onto a single thing as like a form of psychological sublimation (don't think that's the right term either). It's like synedoche but in reverse I guess? (EDIT: scapegoating I guess?) people are refusing to refer to the entire phenomenon and instead fixating on one example pretending the rest don't exist. People can't actually pinpoint the price of a lot of commodities, they just kinda' know that they got less food in their grocery cart or they're bank account has less money. Eggs and gas prices are the only thing I can think of, maybe meat-by-the-pound and milk too. Video games, at least console games, have had pretty clearly pegged prices and seeing that happen is just more obvious to people, especially when it's going from 69USD to 70-80USD than eggs going from $3-5.550 or whatever. People also have the option to not buy a video game whereas they're more powerless about food prices so there might be more political will to complain about it, especially when it's even more obvious that the game prices don't need to go up and Nintendo can't even bother to give excuses why whereas the dairy, meet, egg lobbies have propagandists throughout society saying why prices go up sometimes.

Edit: Might also partially be that video game prices jumping strikes into the middle-class consumer bubble more than food prices. Also kids and younger folks living at home are consciously affected by the game prices because they might spend their allowance, etc. on it while they're not usually buying groceries so there's probably more young people talking about game prices on social media than slightly older, more responsible people.
