That’s not the point of sarcasm. Do you even know your linguistics? Sarcasm has no point - No tonal conveyance really does - but if you wanna get theoretic with it the point of sarcasm is to deliver critique without the sting, or to subvert expectations and deliver a joke. There isn’t a lot of methods of communication were the point of it is to be hard to understand - though some methods are of course used to carry dual meanings to different audiences.
