What does it mean "work"?
If having slaves water your garden makes it grow does that work?
If the slaves feel fulfilled and by all means happy, sure.
So it only works if it is voluntary?
If the majority of sentient organisms must experience the illusion/or actually the freedom of association and freedom as individuals in order to be happy, so be it.
So you'll let me be free if you think I need to be free to be happy or if I think I need to be free?
Well, my permission isn't relevant. Think of societal structures.
Maybe it doesn't matter about your permission/condoning, but you did start a thread about it.
Let me rephrase, is it NOT okay with you if I am NOT free when I want to be? Or do you only desire me to be free when some other entity (a societal structure?) thinks I need to be free to be happy?
