I've got only three, and that's plenty for me. None of mine would be considered "high end", but they're all in great shape, sound good, and play like butter.
Actually, I've got one more in mind, but if I buy it I'll be selling one of the ones I have now. I never was into owning a "collection" of 'em.
In truth, I think I could easily get it down to ONE guitar for the rest of my life and be perfectly satisfied with it. Now, if I could just find that "ONE".
Therein lies the rub.
