My personal take on this issue lies with Part 6. Now this includes major spoilers and anyone who doesn't want to read ahead of the anime should stop here. (How do I put up spoiler collapseables here?) I will throw out tho that it does feel like somewhat of a (retroactive) plot-device.

Throwing Jolyne into Prison was a ploy by Pucci to lure Jotaro into his reach to attain the Road to Heaven. This was written down by Dio in his diary. Jotaro found it, read it and then proceeded to burn it. We do catch a glimpse of it in Part 3 and there is a dead space of time where he could have conceivably went back. Why is this important? Because in Part 6 we learn that Dio included the aforementioned Road to Heaven in it to transcend (to reach Heaven). The most important part here is that it is a journey, a journey Jotaro and Dio both went on to some degree and gained an incomplete ability from it. I say incomplete because we do see what a completed ability grants in the case of Pucci: The ability to *accelerate* time. This should not have been possible, as Pucci's original Stand had a different ability. And it even switched once before while he was On The Road, giving him a total of 3 abilities (that were never active at the same time, mind you). If The World and Star Platinum are truly the same type of stand, it would stand to argue that they would potentially gain identical abilities from it. Dio does stress after all that his Stand is needed to succeed on the Road. I won't go into spoilers how Pucci could have gotten it, I already spoiled enough. Also yes, I am saying that The World was originally just a really powerful and fast punching ghost just like Star Platinum.
