I don't have a problem with fishing near people I don't know. Crowded rivers don't really bother me. Not my first choice, for sure, but I like to make a game out of busy situations, and see if I can hook fish that someone else has passed over and missed. I also like sitting and watching other anglers... sometimes you pick up on tricks that way. When a river is a total zoo, with 50 drift boats jockeying for position, that kills the buzz, I will agree. But I just don't let it bother me much.
