I am willing to bet that the original version from 1977 didn't have a tax dispute as it's inciting incident, or a certain Jamaican CGI character.

You see when Lucas wrote the Star Wars plot the story was huge(He wrote basically from Episode 1 to Episode 9) and he realised that he would never be able to get the whole story into a 2 hour movie..so he picked the 4th part as it introduced characters and had the most rounded story which meant it could be used as a single film.
NB - The 4th part still has the most rounded story IMO.
