While this is an interesting lens through which to view the original question, it is not quite a rephrasing. Suboptimality of our typical mental states for art (or any given task) provides the possibility of improvement, doesn’t tell us whether any given drug* will move us to somewhere more optimal.
(*or even any hypothetical drug—it could conceivably take radical rewiring to improve on our typical performance, although I would find this result surprising.)
