You addressed it from a different angle, but I must add that LW's argument presupposes that religions are a placebo (if not outright medicine) in the first place. Frankly, that's simply not an observable fact. Religions merely replace one kind of fear for another, but the "dread of death" remains. Past short term intoxication, religions don't provide any relief. In that respect they are like drugs with severe side effects, on par with opiates or alcohol. Thus LW in fact has no argument as he encourages self harm and slanders actual "therapists." No wonder, as if I get it, he's a dualistic believer (his conception of God goes way past standard exoteric theism, but it's still a theistic idolatry nonetheless).
