I mostly agree, but the underlying difficulty is not technical implementation, but social (and legal) acceptance. It’s almost impossible to explain the topic to a layperson who’s worried about it but not very sophisticated. And it’s very hard, even for experts, to define “good” and “bad” uses of anonymized-but-segmented (by business/interest/demographics/etc) data.

AFAIK, there are plenty technical difficulties too, e.g. anonymization is very hard.
