My point is that communication requires cooperation between all parties.

If I start using a word in a context that doesn't make sense to you, then one of us needs to bend a bit to keep the exchange of ideas flowing. It doesn't matter which. We just need to cooperate to try to understand what each other intend to mean.

Breaking a flow of conversation to hash out what someone intended with a word happens from time to time. That's fine.

What irks me is when one person, instead of cooperating, makes an appeal to authority to bully the other into using words in their way.
It's certainly *a* solution, but not a very cooperative one.
