The double possessive in English distinguishes between subjective and objective genitives. E.g.,
 I disagree with that opinion of Doug's
doesn't mean the same as
 I disagree with that opinion of Doug.
If you try to make it clear that  is subjective by recasting it as
 I disagree with Doug's opinion,
you at least lose some specificity.
