I doubt that this would affect bone density by that much (3%) in

This was a cross-sectional, not a longitudinal study. So it does not
show for how long these people have had this dietary habit of eating
chocolate. It is very likely that many have eating chocolate most of
their lifetime.
I think that you stress too much those younger years when people are
still about to achieve their peak bone mass. It is also very
important what is the rate people loose mineral from their skeleton.
I have not seen the full study.
It would have been a lot more meaningful if they also corrected for
activity level (the only covariates they mentioned were calcium
supplementation and - possibly - fracture risk [depending on if they tracked fractures or
used bone density as a proxy]).
Have you read the full study? Is that what is said there?
I would expect chocolate consumption to be
higher in an inactive group than an active group. Since I would expect lower
bone density in an inactive group, I would also expect lower bone density
in a group of people who ate a lot of chocolate.
