[Star Trek] I want to buy my wife some nice jewelry for our anniversary. How does buying luxury goods work in a post scarcity society? Do I have a bank account with credits? Does the state cover me?

"Luxury goods" don't really make much sense as a concept in an post-scarcity civilization- you can go to a replicator, produce your wife's weight in gold and diamonds, and do that every day of your relationship. The closest are various industrial components that are hard to replicate, but showing up to your with a litre of rocket fuel isn't the most romantic gestrue.

It seems, from the things we see of gift giving, most is more sentimental  or at least effort based- you might perhaps make a painting of her or replicate the meal from your your first date or something like that. That kind of thing. It's just a cultural difference: the idea of showing your love by getting someone expensive things is as obsolete as showing your love by jousting in a royal tournament is.
