You are not likely to see the statement you are discussing unless you firstly somewhat frequently get into a situation where someone says something like "why do you care so much about privacy?" and then attempt to debate the issue.

It is not necessary to show actual harm from this breach for it to defeat the tacit premise behind the statement you are discussing, which is that their profligacy with their personal data cannot, by itself, reveal any of your personal data.
