I found it particularly interesting that, even though the place described was supposedly free, there were still many restrictions on people's practice of other known vices of the time. He seemed to change common human nature to fit his beliefs of how a perfect society would operate. 
I think this would be a good candidate for preservation because he offers an alternative idea of a state which, even though it was similar in ways, opposed common governance. Something this radical hadn't been proposed in a long time, so it's worth remembering for it's context and outlook. 
One question I have is this, do you think our society today is further from or closer to More's Utopia than his own society? In what ways to both societies differ?

I think today is further from More’s Utopia.  A couple of things, gold and silver meant nothing in his society, and as for today gold and silver can buy you whatever you want. The biggest thing that is different is that EVERYONE works and only uses what they need. Today people use and abuse the different goods without even thinking twice.
