Now that I’m writing this out, it sounds kinda dystopian , but I actually appreciate the doublethink. I believe that pruning “just” (and cousins like “really” “very”, “it” the direct object/noun, “something”) has increased the clarity of my writing.
I think that these words actually do have a use, but only in long recurring interactions where it’s clear that you don’t use these words in everyday communication. Humans are language detectives, and will detect these changes in speech as a signal of emotion. When you’re sincerely emotional about something, these normally vacuous words can be super meaningful. You can even use them in documentation (sparingly), to make a point.
There’s a Tao Te Ching verse about how the wise practice “not-talking”. The implication is that normalizing silence makes words more meaningful: words only carry meaning because they contrast with silence, so if you’re talking all the time nobody will listen to you. It’s a good idea with many implications and applications, and I think it applies to these words. :)
