The difference is not everyone has a toon in range to blitz their own nanos, nor does everyone know how to get clicksaver running properly, but everyone that has AI can buy nanos from the shops whenever they choose.
Again, I'm not trying to say 'omg don't implement this cause its useless'. I think the idea has merit. I'm just trying to understand why someone would choose this option when easier/cheaper methods are available.
If the ones doing the hiring are froobs I can understand that since they don't have access to search terminals, otherwise I don't get it.
