Whereas if you are forced to call when you meant to raise, you don't have nearly as much of a disadvantage.
Your first sentence is accurate - it causes fewer arguments.
The next few are not - it costs an accidental caller more than an accidental raiser.
You're erroneously thinking of it like this: "when I accidentally raise and get 4bet, I lose $12." But that's not what happened. You lost $12 multiplied by your equity.
Likewise, you're erroneously thinking of accidentally calling like this: "when I accidentally call, I would have put that money in anyway." But you actually lost (raise amount minus call amount) x your equity.
When you want to raise, typically your equity is high and the raise is much more than the call.
