I finished the Epilogue this weekend. I had pretty much all my side mission completed. I've found all the rock carvings, dinosaur bones, and dreamcatchers. I've killed all the legendary animals and caught all the legendary fish (Spoiler Alert!...except the new 14th fish because everything I have read says it cannot be caught).
I agree that there are some points throughout this game that makes no damn sense.
1) Why upgrade the camp? Worthless.
2) What happens if a person did not craft all the upgrade-able satchels from the butcher after Chapter 6? Would they ever be able to get them/reap the benefits? I guess at that point not a bid deal, right?
It had been so long since I played RDR1 that I was completely oblivious that RDR2 was the prequel. I watched a timeline YouTube video that outlines the story from the two games. I kind of wish they would remake RDR1 and improve the story a bit more. Or maybe make a RDR3 focused on Jack Marston?
