I'm pretty sure my reasoning was in my comment. Nobody making dinner wants to weigh things out. That's why there are measurements like 'add a pinch', 'just a skosh', or similar. Pretty much the only people I know that measure would be bakers.
The point you're not willing to accept is that there's no dying need to be that precise and using "cup-ish" measures is good enough and works just fine.
Why are you conflating speed and precision? A cup-ish measure would be 200g and no one is measuring that to .05% accuracy.
On the flip side, good luck getting .1g precision out of a measuring cup if you need it.
