I agree we are all a little nuts in a way. We could all just buy a bluetooth speaker and stream spotify and still connect with the music on some level. Good music is good music. Even if you listen out of a tin can with a string connected, you can still be moved by a musical performance.
That said, I think anyone hanging around this website is looking for something better than that. How much better is a matter of taste and we all draw the line somewhere. Your line might be in a different place than mine, but I guarantee most people out there would think we are both crazy for spending more than $40 on an amazon bluetooth speaker or $20 on some earbuds.
@yyzsantabarbara is obviously a big fan of Raal but the point being made is a very good one - some people don't have the best room for a speaker setup, so headphones become a very compelling option. I have enjoyed some Grado headphones in my day such as the old PS500 and RS1. Others I didn't like so much but none have been as enjoyable to me as my Raal headphones. And that's perfectly ok.
