We really dont' need to be "fast" to distribute that wealth, if anything we want to be as careful as possible to make sure it's best used.
And why brainstorm a new distribution solution when there's the sps.
Also imagine the PR nightmare if witnesses/hive founders and devs (which I am 3 in one if there is such a thing as a "hive founder") were to distribute that money to themselves.
I certainely would not be interested to be in a chain where witnesses distribute money to themselves like this. It sets a terrible precedent.
