I’d wager there are daily goods that have far more exploitation than most people would be comfortable with.

But you are right in some cases things aren’t necessities and could probably be limited or cut out. That being said, there’s a morale / mental component too. For example, you don’t need that chocolate birthday cake for your sibling, parent, child, etc., but it is still is considered very important. If it wasn’t there, it could be considered a huge blow and/or insulting.
