Or then it would be the exact opposite: Kamin was a very real person, lovingly transferred to this exotic medium in great detail, and was only going to be implanted into the memory of a compatible person. With the E-D, the probe had a thousand people to choose from, and found its almost-Kamin in Picard.
The transfer probably would run into difficulties of the recipient had inborn reasons to reject it outright. A married man might reject an alien liaison imposed upon him; a particularly swinging single might categorically refuse marriage, let alone the having of children. Hence the scan and the choosing process.
In the end, choice is
usually an illusion...
