Have you been to a really long opera? It’s quite impressive. After hours of pretty intense performance and singing, can you not appreciate the street musician the day after? Do you have a strong desire to go to the opera again the following days?
Replace with food and its even clearer. Going to some top of the line Micheline star restaurant _will_ alter how you look at food for the rest of your life.
Watching a movie in blue-ray full quality no compression _will_ alter how you appreciate streamed movies for the rest of your life.
You can still appreciate it for what it is, but it will forever have that relative smallness.
Interestingly I don’t agree with you and that’s what I would call elitism.
Food is a great example as I know I’m personally able to appreciate a great and complex meal at a high end restaurant and still enjoy some fast food.
It’s the same for art : does having a favorite book/movie/music/videogame/… makes you unable to enjoy other books/movies/music/videogames ?
Maybe as a whole its a poor example though because enjoyment of food is a multi-dimensional problem. Whereas obliterating a dopamine receptor is one dimensional.
