I know that words are largely arbitrary and arguing terms isn't very valuable but these phenomenons already have fairly commonly used names.

OP writes about conspicuous consumption/leisure, not really luxury. Similarly, while a Birkin bag could be considered a luxury good, its defining feature is being something more, the artificial scarcity and increased demand with price amke it a Veblen good.

Also, things you can buy with attention aren't really expensive, they're just constantly priced. That is you have 10-14 hours of attention a day, and you use it or lose it, every minute of attention is largely the same, with a little ADHD you can switch quickly. Listening to a concert online and going to the philharmonics costs about the same in attention.
