I'll make the claim that gibberish is distinct from non-logic. Its a nuanced, takes practice, and not something that will always land in all contexts with everyone, but there's something there to become skilled in illegibility. To be logical and legible is to be straighforward, to be illogical and non legible is to pack in knowledge that takes time to unravel well beyond the immediate encounter. It is something that works on you over time as you repestedly come back to it. It does, however, assume that there's something of value to unpack. Being immediately clear has value, of course. But I do think there are contexts where knowledge transmission shouldn't be immediately clear to onlookers that wont put in the work to understand. Can it be pretentious? Sure, but again, moving beyond that immediate assumption can open up possibilities.
