Network Effects (Structural Defensibility)
When a product becomes inherently more valuable to every user as more people join (WhatsApp, LinkedIn, Uber)
In Simple Words (Zero Jargon):
When your app gets better simply because more people use it (e.g. WhatsApp is useful because all your friends are on it, making it impossible for a competitor to copy easily).
What You Get: A compounding moat that makes your user base virtually impossible for competitors to steal.
