In regards to token types, the absolute fairest way is to have the currency and ownership amounts based on current M. Current M distribution has a backlog of embedded currency and ownership value from CON, "old" CK, and so on. Please, don't make this confusing/stupid and go with gold or anything. And I own a lot more gold as a % of total gold than M as a % of total M, so I'm shooting myself in the foot here, but really M makes sense as the base.
Agree with all this (and I also have more gold than M)
To illustrate, if someone owns 1% of M right now, they will own 1% of CKM (money/currency) and 1% of CKO (ownership). Once the CKM and CKO distributions are done to the depository wallet and accounts, you delete M.
I have a feeling that "M" might be hard coded as the base currency, but maybe someday that can be fixed.
