I always lie about understanding double entry accounting.

” If our reputation engine can also offer respect for the privacy of individuals, I guess that would be the icing on the cake.”

I like to have the icing first.

“[A camera] …in my pantry seem less privacy-invasive than one in my bathroom. Considerably more importantly, a camera under my auspices seems less privacy-invasive than one under police auspices.”

Less by a very small amount IMO. I put tape over my pc webcam.

“The black-market nature of agorism definitely competes with the goal of extreme transparency”

IMO both extreme privacy and extreme transparency are proper and necessary, as may be some combinations in between, for different applications. It is fundamentally impossible to serve all needs with one extreme or the other or any single compromise.

People will often waive privacy and even security when sufficient incentives are offered. I would rather that be regulated by law rather than fully open to constant private renegotiation simply barbecue that gets exhausting. Automation can easily exhaust any resistance we have.
