Human experience is broader than you can imagine. Through reading, I regularly encounter new ideas and concepts that I never could have derived from my interactions with others. Through meditation and contemplation I have experienced strange and fascinating modes of consciousness that are available to anyone willing to sit still for a while. Casual travel has led me to an endless number of beautiful empty places, places whose very lack of humans made me feel completely free. Making physical things as a hobby has made me deeply satisfied in a way I never have felt when dealing with people.

None of this has required much in the way of socializing, in fact excessive socializing would actively interfere with these activities.

I reject your implication that a highly social life is better than a rich, mostly solitary life. It’s different, but not better.
