Consider if you had a concussion on the right temporal lobe and had hypergraphia as a symptom of the resultant temporal lobe epilepsy. I'd write everything I'd want to write regardless of who complains. Philip K. Dick was one such person.
It depends on what you care about. If you're writing purely for yourself, then by all means, go ahead and do so.
I've found there's a balance to be found in listening to others vs yourself. Usually, if multiple people give you the same feedback, there is some underlying symptom they are correctly diagnosing. But they may not have the correct diagnosis, or even be able to articulate the symptoms clearly. The real skill of an author/editor is in figuring out the true diagnosis and what to do about it.
In the communication example, this means rooting conflicts in the true personalities of the characters and/or their context, so that even if they sat down to have a deep chat, they still wouldn't agree. E.g., character A has an ulterior motive to see character B fail. Now you hint at that motive in a subtle way that telegraphs to readers that something is going on, without stopping the action for what would turn into a pedantic conversation. At least, that's what I'd do.
