That is true. However as with every decentralized currency (which those Nxt Currencies will be), they start with a social contract. That is, people will only have faith in the newly created currency when they can trust the stability and adherence to the social contract of the currency.

Currencies of the MS are not supposed to change once they are created AND in production.

Only new currencies would enjoy new properties later introduce than those initial ones.


But yes, people are free to suggest and to shape the decentralized nature of the Nxt economy platform.
