That’s such a silly argument. Nobody is forcing you to buy Fortnite skins when your kid is starving. Monetary incentives are how the things people want get created. Yes, there would still be plenty of content on the internet if we banned monetization of digital goods but it would be overwhelmingly incoherent and low quality.
It would also destroy the livelihood of millions of people. What about their children? Do they not deserve to eat?
Edit: I should add that it would be more reasonable for you to say “food and healthcare should be available to everyone”. That’s not an unreasonable statement.
