I’d love to see the ACU retired, or reworked, in light of this; giving ACU members the ability to control the ACU’s accounts by expending their credit balances might be interesting. I might spin up a fractional reserve bank organization, if I can find suitable investment targets, too.
Anyone should feel free to propose a reworking of it. I didn't have any specific idea of what to do with the interest income, beyond "put it out there and see if anyone came up with something".
