Earlier quoted context omitted.
Monopoly on life-saving medicine created by a scientist? Sold at prices out of reach for most people?
Still better than their non-existence.
I was asking if, given their existence, it would really be "OK" to have one person control it. You came back with suggesting its better than them not existing, which is fine, but is only relevant to this discussion if you can prove that it wouldn't have existed without the monopoly. I am doubtful of this.
Its easy to see the error in this logic since it basically applies to all things: a monopoly on food production is better than food not existing. A monopoly on housing is better than no houses, etc etc.
