>> the myth you are an individual completely separate from the world outside

Aren't you?

You were born alone, you will die alone, nobody can live your life for you, nobody can share the responsibility for your decisions.

You are alone. Everyone else is a script. The only thing that matters is whether your actions make you happy without a hangover. Why would you worry about anyone else's judgments?

(Sick people, who are made happy by abusing neighbors, will always exist, but they are, luckily, not numerous.)
