Your logic is wrong, because iPhones and iPads are creative devices where photos are created. Therefore, your understand of Steve Jobs intentions are wrong.
I am probably too plain for this, but to me there is usually very little creativity involved in re-ordering a playlist. The rather massive replacement of radio DJs with automated systems is a testament to that.
The creative devices are the MacBook and iMac.
It's this reason you can't organise your songs on your iPod without using iTunes.
