Hi, I have explored a lot of these concepts already with the idea of a 1000-man island.  I choose 1000 because with 10 people it's not likely that any currency is needed.  Everyone knows who is pulling their weight and not; instead a reputation system would prevail.  If you are the main hunter it's likely you can ask the others for whatever you want and get it.  If you are a louse, you will struggle to get help. 
 
But with 1,000 people it's not so obvious who is contributing what. 
 
As well, I extended your parable of the tickets, and went on to liken bitcoin to a sacred "rock" on the center of the island and the latest cryptonote currencies to actual hard mined gems.  Feel free to check it out and provide some commentary if you like:
