The world is dangerous and enemies are everywhere — everyone has to protect themselves. A fortress seems the safest. But isolation exposes you to more dangers than it protects you from — it cuts you off from valuable information, it makes you conspicuous and an easy target. Better to circulate among people, find allies, mingle. You are shielded from your enemies by the crowd.
The L18 doctrine in modern practice: the operator who hides from the public loses more than they gain. Anonymous-writing / anonymous-OSS / anonymous-any-platform was a 2010s-to-2020s pattern; the consensus has moved toward visible-by-default, name-attached. The exception is the high-target-profile actor, but L18 mostly says don't be that.
Greene's direct contradiction of fortress-thinking. The crowd is its own armor. Naval's people-as-leverage principle applies here — visible-as-many beats invisible-as-one.
