> So trying to make the language more "compact" would likely just waste precious brain-cycles on the compression step

If you learned this new more compact language as your native language or to native fluency, I don't imagine you would need to go through a compression step, since all of your thoughts would already have happened in the compacted form.

That raises the question of why it seemingly hasn't happened already.

One option is that what you're describing just isn't possible, that humans are already butting up against some kind of limit which is not avoidable simply by being raised with a different language.

Another option is that one can be raised to think in "pre-compressed" structures, but nobody does because it's a bad tradeoff, dropping "general thinking" performance with a worse impact than any "faster speaking" benefits. (Such as being simply slower, or more error-prone, or more demanding on attentional resources, etc.)
