I think the problem lies with this statement:
"...for the privilege of sharing a field with hundreds of people you have neither the energy nor the inclination to get to know?"
Well, see that's the thing, for me, meeting other campers is what makes it so great! I like the fact my kids make camping friends. I like the fact that friendly campers will come to your aid if they see you in a spot of bother (helping put each others tents up in high winds, lending mattress pumps when yours breaks etc etc).
No, I don't want to make a new bestfriend on holiday but you meet some really lovely people AND often larger families who 'know what it's like'
