If you wanted that to be a real argument then you should have done the maths yourself. Without those maths you are doing nothing but gratuitious handwaving. I've done them for you and they prove me right (and you wrong at least where you say "hardly more than for bivalent logic").
Oh, and if you want to know why people don't want to find more "useful" operators than what they're used to from good old two-valued logic then I have a hint for you too : it's because they all immediately sense that their brains are not up to it as soon as they actually try (and my actually doing the maths has very clearly shown me why - so as you suggested to me "perhaps give it a try").
