Planets move in elliptical orbits. If the universe condones it, it can't be all bad. This might be true in some cases, but certainly not all. The charge of deliberate obfuscation is more often meant to defuse work people find threatening because of its unconventionality, and to compensate for an unwillingness to see things differently. But it is also an unfortunate feature of human nature that people gravitate toward the familiar and avoid the unfamiliar.
Mediocrity is rewarded with far greater frequency than originality.
Nevertheless, an artist who attempts to rebuke or avoid mediocrity by being deliberately obscure is risking nothing but impotence. Choice doesn't really enter into it. To defamiliarize the familiar. To boldly go where no one has gone before. The stimulus that brings me to a piece of paper in order to create something new is not a social impulse.
