Mihawk is the greatest swordsman in the world, which means Shanks had to be very close to his ability- but crucially Mihawk doesn't care about the world as much as anyone else would and is practically a loner and respects Shanks just for keeping up with him in the duels. Law is far too enigmatic and ambitious to be like Mihawk, even if Luffy is the next Shanks/ Roger. Law is quite unique in that he doesn't really have any open goals other than going for the Grand Line, he's almost a pirate version of Aokiji, who'd rather be sleeping but has motives and history of his own.

Luffy did declare Fishman Island his territory, but the King clearly said the Straw Hat Jolly Roger was something they could borrow if needed, Whitebeard declaring FI his land is very different to Luffy doing so- WB had thousands of pirates and allies to protect the place, Luffy literally has about ten people he can count on. Even Shanks' power is unknown, since we've mostly seen his own ship. An Emperor cannot have one ship, surely.
