The reason for that is obvious.  Content labelling only allows a person to
filter what he sees himself.  However, most people are not satisfied to
filter out what they dislike for their eyes alone--they prefer to censor
what they dislike at the source, so that _nobody else_ can see it, either.
Content labelling does not provide for this type of censorship, and so
nobody uses it.
