I can see your argument, but would disagree with where. Cursive is really not meant to be artistic: that’s covered by calligraphy. There’s no reason to cover it in advanced lot: I suppose if you’re researching original sources like journals, you’d need to know, but that puts it at college level.

The most important thing people still need cursive for is a signature, but we don’t teach basic life skills anymore, plus a signature doesn’t seem to need to be recognizable anymore

That being said, I do think it should be taught for a bit longer. Ts still the most efficient way to take notes, it’s still in common use by previous generations, plus the all important signature
