Agree with @0xc0de4c0ffee, we should lock in the issuance forever. Doing so would make us look a lot more trustworthy. The income can still be increased by increasing the value of the token. Any salary can be paid from the DAO (which needs its own income for the whole thing to work anyway).
I don’t think there is a democratic problem in locking the issuance rate forever since later managers are free to create a new token with other rules.
Best IMO would be if we could technically prevent ourselves from ever changing it - or we could require a 10% quorum of all users and 80% approval (super-duper difficult and if someone pulls that off they must have a point).
