Yeah, breaking into an existing social circle without having god-tier confidence and social skills is pretty much an exercise in futility. People are very comfortable with their isolated lives even if it makes them miserable. We can organize all we want but it doesn't change the fact that most people are too full on junk-interactions to care about irl.
If you want to make connections, you have to accept you'll be the villain of someone's story. "Some fucking weirdo tried to talk to me about coffee at the mall today." Embrace it, be the weirdo who makes people uncomfortable. The world is too obsessed with avoiding negative reactions that we never try for a positive one.
