Personality matters wherever relationships matter, and that is in any community.

>if people come here to build something better together, it will become a form of community social art - a solid base for the architecture.

The architecture requires infrastructure that supports a gallery to be built upon. There is more to it than the UI that most people evaluate.  

>all of this perception of jealousy and self interest being motivating factors of the marketplace, well, isn't that just a mirror? 

It is all a mirror isn't it? I don't hold much jealousy personally though, not since I was about 16 - but then I have worked since then and been relatively self-reliant since then also. 

>not everyone has that mindset. 

Perhaps not, but,

>if people treat steem as if its a place to cash in, I feel this lessens the dignity and perceived value. 

This is an expectation/feeling of the way things should be, which is fine for you but not necessarily for others who might think quite differently. this sets up personal conflicts and issues because,

>I am here for the people and the interaction between minds all bent to a similar purpose. 

You can feel that your purpose is being undermined by those who don't understand the value that you see. 

>sometimes it isn't about the money.

Value has nothing to do with money. Money is just a token.
