Speaking as a wife who never understood the attraction of expensive beauty products but has friends who love some irrational things, you might want to let that one go, unless your spare time is dedicated to home improvement, caring for the less fortunate, and/or managing your investments, because you don’t own hardware suitable for gaming, a motorcycle or a high-performance car. And even then, you probably still want to let that one go. You likely also spend/waste money and time in ways that your wife finds less than rational. We are socialized to nag you a bit about it, but ultimately, not to take action against our men’s “harmless” wastes of money and time. Separate checking accounts are underrated. My grandfather kept one paycheck a month, out of which he paid the mortgage, and gave the other to my grandmother, who paid all the other household expenses. What happened to the rest in each of their accounts was pretty much their own business. * if her brand loyalty is to something sold by an MLM, then you do have cause for intervention - “I can get a fantastic discount by becoming a seller!” is the trap that catches a lot of women.
