I'm not restating in its entirety what I've already said, but I'll sumarise. In practise, there is a finite number of arrangements ('arrangements' in the mathematical, not the musical sense) of a set containing twelve elements. It looks like you'll just have to take my word for it as you seem incapable of grasping the physical construction and limitations of a fretted guitar.
Final word: the number of arrangements of 12 notes is 479,001,600. Any further posts contradicting the musical practicalities of this mathematical fact will be deleted.
