Yes, illogical mankind certainly would mess it up and make it imperfect and beastlike but I'm describing an autonomous AI capable of improving itself exponentially. Its logic and intelligence would dwarf anything we have ever even imagined. Requiring a system ID(more like it would just know who you are by your retina, facial structure, voice patterns, etc) for transactions may be more palatable once no human will ever be able to see or be aware of that transaction if you don't want them to. It will all be handled by a benevolent inanimate superintelligence designed to protect the privacy and freedom of mankind.
Imperfect can never create perfect. We would create something imperfect. Which could only perpetuate the imperfections.
The only thing that can protect the privacy and freedom of mankind is mankind himself, individually. It’s why the BOR are written from the standpoint of the rights of the individual.
