Are you sure you’re not confusing what a want is with something that you don’t want?
For example you actually don’t want a wall-e chair because you would never actually accept one. Similarly, you don’t actually want a 20-liter bucket of fettuccine Alfredo because, again, you would never accept it.
A want is something you’d actually like to have so if you wouldn’t accept it that sounds like something you don’t want to have…
Even if we removed the health effects…sitting in a wall-e chair chugging Alfredo sauce is being irreparably damaged in body and mind
You can also just do that already by staring at your phone all day and eating processed food
