I've seen this type of comment in scifi threads. It was about that one planet-consciousness in the Foundation series, some guy thought it would be hell to lose his individuality. But I think that people are confusing privacy or autonomy with individuality.

Also the fact that individuality is already illusory to begin with -- we are social animals, and if we truly tried to be absolutely individual, we'd end up as a feral child or some bizarre hermit. And ironically we live in an age where we are so alienated not just from others but our own selves, and our very species-essence as well

This comment made me realize that Odo's people aren't so different from the Borg.
