Disagree. I am a native speaker of Urdu, and Urdu is effective only with significant English loan words. The Persian alphabet also makes little sense - we pronounce seen and suad the same way but write them differently thanks to the Persian alphabet being forced on a language that wasn't meant for it.
And as for the using persian script for urdu, without going into political stuff, I think it is a huge advantage - Persian script is not only used for Persian and Urdu, even Balochi, Daari (Afghanistan), and Pashto uses Persian script. Moreover, by virtue of knowing Persian script, it becomes immensely easy to pick up Arabic (at least reading it).
Then there are few other languages such as Sindhi (Pakistani Sindhi) which have a Persian-based script (few other characters on top of Persian which are specific to the language).
Which means, if you can read Urdu, with little effort, you can start reading Arabic/Balochi/Sindhi which means you can read literature from Pakistan all the way to Morocco.
