I think the OP is actually a joke. A riddle of some sorts that has all the answers, but the answers can't be filled because of a twisted fate of irony.
I believe Joy Boy was fight the Ancient Government but he had this running gag of always being on time. However when the world needed him the most. He was late. So therefore it set off a chain reaction to where the world is today
Roger laughed because he was too early. Luffy will laugh because he is on time. Being at Laugh Tale at the right place at the right time will show the gang one of the ancient weapons hidden. On the island.
