I’m more inclined to believe its a matter of genetics/gene encoding that makes some men more susceptible.
For example, in the following study, men with the more common A-allele experienced more side effects of alcohol than those with the G-allele. And related to this, “Among the A-allele homozygotes, there was a greater reduction in several subjective effects during the finasteride session compared to the placebo session”

Now I’m making a stretch here in comparing alcohol dependence to Finasteride effects, but the fact Fin affected those with the A-allele moreso than the others says something to me that this drug operates at the genetic level and thus we may all share a common genetic trait that made us susceptible to the permanent side effects.
The other reason I believe this is due to what Dr. Shippen told a former patient:

“He believes that Propecia switched off a gene or something like that, perhaps one that controls the conversion of testosterone to DHT”
So in no way do I think this is related to poor sleep, low bodyweight, depression or other pre-existing conditions one may have had. You guys all know how you were before the drug, and things have changed since taking it. The drug is the common factor here, not – for example – one guy being fat and the other skinny. It affects our HTPA, our endocrine system, prostate and neurotransmitters… THAT is the common factor.
