Found the same problem myself in February -had purchased the upgraded 12mm nut/washer in anticipation.
When I tried to undo existing nut I was on my own so put soft piece of wood between wheel spoke & swingarm. Fitted 600mm extension bar and a length of steel scaffold pipe over this--couldnt budge the f****r ! So like you reasoned that if brute force & ignorance wont move it then I will leave until such time as sprocket needs replacing & get local friendly garage to shock it loose with air tool !
