I think this is an interesting question.

It gets to the heart of the tech-entrepreneur dichotomy quite well. My initial thought was well, yes, take three months off and he could easily do a decent app - but the opportunity cost would be enormous

But this just assumes there is a single coding based dimension (the Blub dimension?) - in reality Jobs stopped coding in Objective-C a long long time ago, and started coding in vision/people/organisations - a much more difficult programming environment and one that gets really really hard to scale.

I can barely program in this language on 6 or more cores. Jobs managed it at 100,000 cores.

So my answer is no he could not write an iOS app - but he could write really good applications in HomoSapien (Enterprise Version) - and there is hardly anyone who can get that to even compile.
