> But I like both cursive and Arabic

Just a personal esthetic (unpractical) preference.

> It's not optimized for printing and digital fonts I agree. But you can't say it's not useful for daily use.

These two sentences contradict each other. Daily use means printing and reading from screen.

> It's so much easier on paper.

Only if one writes by-hand. Which is unpractical since like press printing has been invented.
