Our reading
An editorial interpretation.
The speaker declares an intense, gloating desire to possess something, repeating the claim for emphasis. The theatrical 'Oh yes' gives it a relishing, almost villainous flavor, as though wanting has hardened into certainty. It is a self-assured vow of acquisition rather than a hope or request.
