How big is a field? Exile for committing a crime is probably the worst thing that could happen due to MC being able to grow the best tasting food, is able to make like anything and is able to protect and manage a village. Yeah, I definitely wouldn't risk anything to be exiled from a place like that. Currency also changes things a lot, as it allows people to raise their status based on what they can offer. I don't think that is too bad considering it is the person who is doing the job who gets the money. No intermediaries and other bullshit taking from the person who does the job. It should prevent the build up of money with any one person.
I still think that women will want to use their tokens to have a kid with the Chief and now I'd say it'd confirm it with the list of what you can get for 1 medal.
