First off, your "high-and-mighty" grammar doesn't help for one to want to listen to your arguments. If you truly want people to listen, it is my advice to act more humble, and with more reserve.
Secondly the entire concept behind your arguments are based off of not just opinion, but off of personal research that you have not accurately laid out and described in an organized way. This is something many on this board have failed to achieve. Even the ones i have seen who have laid out there theories as such, don't base their theories on provenance. They base them on third-party research littered with discrepancies, opinions displayed as facts, and mislead conclusions.
If you want to disprove something, you yourself must present the information in an orderly manner so that one might be able to understand your argument and where your views on the matter come from. Even then if you are not fully willing to hear out what others have to say, it is self-centered to think that others should listen to you.
I will agree that when working with such, provenance it the absolute key. But when the information related to provenance seems non-assistance, you keep searching. When you can't find something you look for it. Otherwise, you have given up and lost the game. Just because your research and your battles wound up short, that does not mean you should impose on others your opinionated ideas that working with the code is useless.
As for provenance, the arguments made on this board leave me to personally believe that there is a story here worth searching for, but one that many on this thread and this board are not willing to uncover. Though i myself do not work on the ciphers, the information leads me to believe that whoever does and is successful, will discover something worth more than a simple materialistic value.
