There were indeed coincidences in the OT, especially Star Wars, but they seem to be of another kind. There was a reason for Ben and Luke to be in the same area on a desert planet, since Ben was watching over Luke. There are potentially good reasons why the Droids land near Luke and Ben, since they could have Ben’s coordinates and were piloting the pod in that direction (as the Radio Drama suggests).

The explanations you point weren’t explained until many years Later. In the case of the pod landing near Luke, it was a fix by a writer other than Lucas. In the story presented in 1977, that pod is in an obvious free fall. The NPR drama came out four years later and Ben’s reason for being on the same planet wasn’t explained until decades later. If the first film gets a pass because things are assumed, or left unexplained for decades, or there are “potentially good reasons”, then the new film should be given the same pass.
