I suppose it would be up to the musician's interpretation and understanding of proper fingering techniques. It's pretty obvious that tab style music makes it clear, and I've seen sheet music specifically written for guitar that notated the finger you're supposed to use beneath it (with numbers 1 - 5, 1 corresponding to the thumb if my memory serves, which you never use for guitar). There are countless pieces of complex music, especially in classical music that are fairly difficult to play by ear. Knowing how to read music opens the doors for being able to play anything you want as long as you can find the sheet music. Reading music is also an excellent brain exercise.
