Well take away theory, you can still play.If did`t have ears can you play.No cause you could not hear.It is a good thing to have a good ear for music,i don`t care what anybody say.
Why are you choosing to fight an opponent that's not there?
As far as I've read no one said that it's a bad thing to use your ears for music. On the contrary I ALWAYS encourage people to listen at least as much as they play. Listening is as important as saying something.
That said, increased knowledge of any language comes from listening AND from studying. If you just listen, you'll only hear so much and miss a lot, so listening has limitations.
Also, there's another factor to all this and that's in being able to hear more complex music and rightly discern what is going on. Maybe that's for your own understanding and maybe it's to better communicate with others who perform more complex music or to teach others, too.
You don't HAVE TO KNOW theory to know how to play music and there are some (although they're rare) who know very little and yet are great musicians (Todd Rundgren is one person I can think of), but that's no excuse to limit yourself if you have the desire to know more. I know some players who "just play" and they've made a decent living for themselves for decades, playing the same old blues licks over and over. And for every one of them are probably hundreds of others who "just play" and have all but hung up their guitar for lack of knowledge; they hit a wall and have no motivation to get around, over, under or through it.
I choose to not be one of them.
