Secular humanism and consumerism are also ways of coping with the threat of nihilism after the collapse of theocracy, by positing subjective meaning in our creations (including the creation of our egos). But Buddhism rejects those subjective meanings as illusory, and spoils any attempt to find subjective meaning, by dismissing the self as a confusion.
The goal in Buddhism is to free our empty selves from that confusion, to achieve nirvana which is a state of paradoxical, inhuman consciousness that enables us to stop worrying about the meaninglessness of everything. Nirvana would be the ultimate consolation and acceptance of nihilism, and it frees us from the world by ending our cycle of rebirth.
So I'm not sure Buddhism is best thought of as just another way of coping with nihilism. Buddhism is more radical than more commonplace secularism.
