> But this was not for ordinary people (peasants) or even accountants, where practicality matters.

All peasant societies were illiterate, including Latin script adopters. Completely irrelevant to Arabic.

"Or even accountants" - apparently, Arabs didn't trade! It's not like Muhammad himself was, you know, a trader and an accountant...

> With some training it's possible to read Arabic texts. But this requires more mental load and practice compared to other alphabetical systems.

Perhaps your brain is too slow. I and many other bilinguals read Arabic even more quickly and efficiently than Latin-script languages. The words are terser and are read as units as opposed to the inefficient character-by-character Latin system. Speed-reading doesn't exist in Arabic because Arabic is already speedily read.

> It may look good, but it doesn't matter for daily use when one needs to read and type a lot.

You just said it was objectively horrible looking above. But consistency cannot be expected of a jumbled mind.
