I'm the only person in my family that owns a desktop myself, but my group of friends is mostly a bunch of desktop users since one of our primary use cases is PC gaming (although mine is also a workstation for software development and some light video editing).

Regardless of their quality, you can get a basic no-frills laptop for $400 and be able to carry it with you - or you can spend that much on an equally no-frills (though still arguably better specification-wise) desktop and have it stuck wherever you put it. More people tend to favor the portability, they can have it at the kitchen table or in front of the TV - some people don't even own a proper computer and rely entirely on smartphones and/or tablets.

Desktop computing outside of the workplace is increasingly a niche, one that isn't going away as long as PC gaming remains but to argue it's not shrinking is delusional.
