It's like the blockchain's way of saying, "What's done is done, son!" You can't go back and change it, even if you wake up the next morning like, "What the hell was I thinking?!" It's the ultimate accountability tool – no more blaming your mistakes on someone else. You did it, it's on the blockchain, and now you gotta live with it.
Example
"I accidentally sent my crypto to the wrong address, but thanks to immutability, I can't do anything about it. Guess I'll just cry myself to sleep tonight."
"Immutability is great for keeping politicians honest. Can't go back and change those campaign promises once they're on the blockchain!"
