french only works as a means of communication because it has internal rules that are objective (as in different people understand the same/very similar thing when hearing/seeing a symbol/word).

No, natural languages are not objective, they have semantics, contexts, all that.

reducing human experience to a blackbox kind of singularity is a highly individualist take.

Bombastic! I'm definitely and individualist and I don't want to have anything in common with collectivists.

You can work on understanding each other without forcing anyone to fit into your definition…

Which is what's individualism all about.

See above
Individualist as I use it means the over-estimation of individual autonomous agency, as in "i'm solely the product of my very own decisions, which are independent". This is a mystical view that supposes a god-like agent. For example the concepts and notions you are thinking and following this convo with, are a social product you obtained via collective processes. The more conscious you are of this fact, the more free you become as an individual agent (because you understand your conditionalities and because substantial changes have to be driven collectively for a collectively conditioned entity).
In "my" definition above individualism is more like a contrafactual idea that surrenders the possibility of mutual understanding with it's "I'm my own magical creator and creation"
