Hollywood is a great example of frivolous waste that is producing movies that will never be watched by anyone in 100 years. Not to mention provides little to negative value right now. If there wasnt infinite entertainment, you could argue that hedonism is the correct ethical system and we should invest into entertainment, but there is enough entertainment to last multiple lifetimes.
We can probably expand this to things like coffee, but you could argue that it provides value.
How about firework shows? Veblen goods?
Would love to see low-impact entertainment become a thing.
