You asked why someone would think aggregating would make it better.
Aggregating protects privacy when done properly.
It seems pretty obvious to me that sharing individual data is orders of magnitude worse than sharing aggregated data.
If you think they're the same, then you don't seem to value the privacy that aggregation provides.
So what am I misrepresenting about what you said?
I'm tired of false equivalences. One thing that's maybe slightly bad, and another thing that's super-super-bad, aren't equally bad.
