Existence itself is a competition. "Survival of the fittest" implies that some level of fitness is required to survive. Few macroscopic organisms can go more than a few days without consuming some other thing that was living not long ago, whether plant or animal.

It has problems, but by this point, it's well-proven that living under dictatorial fiat disguised as utopian mythology is far worse.
