Now you're just being deliberately obtuse. The entire reason I explicitly pointed out the potential for abuse was to head off the "Charity of Bob's Kids" comment.

Obviously such a system would need significant safeguards- this is something we're both fully aware of as intelligent human beings. Mentioning them now is just a strawman unless stated as the overall opinion "it's 100% impossible to stop abuse".

On your last point, I find it silly to assert that a belief in humanities ability to overrule animal instincts is somehow "Pollyanna thinking". Everything we've achieved thus far as a species has been based on that belief.
