If you haven't had a transformative psychedelic experience yourself, it's understandably hard to imagine the benefits.
LSD's benefit as an anti-depressant is indirect - that is, it is used for ego separation through counseled meditation, not through regular dosage like typical anti-depressants.
Ego separation is a very strange and complex thing. The ability to disconnect from being a human with our social pretenses and look at the world from (essentially) an alien's perspective is incredibly powerful. Such an experience changes people forever, usually for the better(through good
counseling).
In addition, seeing as being deeply involved in ones work often leads to essentially mental tunnel vision, the same properties described above provide insight and inspiration that ones mind might otherwise occlude(whether we want it to or not).
