I don't disagree with you. If it was the only extant copy, I would urge every effort to be made to secure it for the country wherein it originated.

Since there are several copies, and this appears to be one of the later ones, it would seem to be unrealistic to spend vast sums of taxpayers money trying to get it back from abroad.

(And just to be a teensy bit churlish, if the UK made serious claims to ownership by national origin, the poor old British Museum would lose its Marbles...)
