Ban the entire business model. It’s neither a product nor a service - it’s a scam. Games make you value arbitrary worthless nonsense. That’s what makes them games. There is no ethical form of attaching real-world prices to that charade.

‘Oh, but if it’s only cosmetic…’ Y’mean proof that people can be made to want stuff, even if it doesn’t do anything? Entire games exist to funnel people toward emotional response, and some of them make billions. Saying ‘it’s just hats’ is the opposite of a defense.
