If you enjoy playing the guitar then you shouldn't quit over the bar chords IMO. It's true that bar chords open a lot more options but I would suggest it's not required learning to have fun and enjoy playing guitar. You can play a number of songs with open chords and power chords and have a lot of fun doing so, and there are scales and lead riffs to learn and enjoy as well.

The question is do you enjoy playing and learning the guitar outside of the challenge with bar chords? If so then don't let the bar chords ruin it for you. Perfect the open chords and scales and maybe the bar chords will come later.
