Why should you learn the skill of guitar tuning? Because music is sound! The better your guitar sounds, the better your music sounds.
When you first learn to play guitar you develop the habits that make you a success or failure. Tune your guitar every time before you play or practice, and any time you think your guitar may be out of tune!
If you play guitar untuned you just won't sound good, and it'll be impossible to develop an "ear" for pitch. After you play for a while your ear will grow accustomed to proper pitch, and you may be able to tuneup with your judgment alone.
Pitch and rhythm are the foundations of music, and the rest is built upon these using knowledge for bricks, and practice for mortar!
