The equilibrum you speak of won't protect steem power holders as the CN community will take a lot of market share away from steem still. Many projects will develop around this token and thus it will be directly competing with steem.

@ned and the devs at steemit @vandeberg,etc..need to make sure that these tokens can only be bought and sold with steem. Maybe a mecanism like rootstock where you can exchange RSK for BTC and back would guarantee that these tokens are only redeemable for STEEM and that you need to buy STEEM in order to acquire them.
One thing that many say is that steem has the community and you can't copy a community, this is true however one reason why this community is so powerful is that we all use the same token and all want it to suceed, implementing a token for each sub communities could turn out to be very divisive if this tokens doesn't directly benefit steem power holders.
