All agents are considered equal,

If I contract a neurodegenerative illness, which will gradually reduce my cognitive function, until I end up in a vegetative state, do I retain agent-ness throughout, or at some point lose equal footing with healthy me in one go? Neither seems a good description of my slow slide from fully human to vegetable.

with their individual utility units converted to some social standard. For example, Agent Alpha receives 100 Alpha-Utils from the average day, where Agent Beta receives 200 Beta-Utils from the average day. Both of these are converted into Society-Utils - let's say 10 Society-Utils - making an exchange rate of 10 Alpha:Society and 20 Beta:Society.

What is an "average day"? My average day probably has greater utility than that of a captive of a sadistic gang...
