What Wilde captures here isn't merely permission to be odd—it's an economic argument about scarcity. There are only so many ways to be human, and your particular configuration of peculiarities, sensitivities, and accumulated failures is genuinely irreplaceable. The real cost of imitation isn't moral failure but opportunity loss; every hour spent performing someone else's version of competence or charm is an hour your actual self remains undiscovered by people who might actually want to know you. A friend once told me she spent three years at university mimicking a popular girl's confidence, only to find that the handful of genuine friendships began the moment she stopped—not because people suddenly approved of her, but because she finally had something real to offer.
