Yes, those are good points.
I would have advised The Emperor in 1813 to accept Metternich's offer to mediate Peace, and to accept the best terms of Peace that could be obtained. I would have advised, "In War, France has prospered economically. With some years of Peace, France will dominate Europe economically, and that is something that England cannot prevent."
Finally, I would have said, "And, Sire. If you grow tired of life in a Peaceful Europe, you can always go to live in New Orleans ! The people there love you and would be thrilled to have you live in their City. And you would certainly be King of the Mardi Gras, at least! Mayor and perhaps Governor, if you like ! "
