On the one hand, it seems silly to debate electric cars versus trains while we have gasoline cars on the streets. On the other hand, I like that we focus our news on the low emitters, so gasoline cars drop out of popular culture. To change a paradigm, it helps to speak with assurance from the new one.
Some things can lead to benefits, without themselves being beneficial.
In psychology, diagnosis is sometimes like that. It can lead to treatment, accommodation, and funding, but the diagnosis on its own may not be beneficial, may cause harm through stigma, and may not be necessary to access the benefits.
The alternative: when possible, provide the benefits without labeling the person as disordered.
