It sounds good though the holder of the master key/founder has all in his hands. founders of big communities can still take the pot and leave. Noticed it more than once past year.
Like the pots/different fund saving options idea. More like with bank apps. Wish similar is possible for content written. I wonder how many keys get lost within communities for real. How about the average Steemit wallet? No protection against being hacked, which is for sure not due giving the key to an untrusty friend. Leaks are everywhere: gives, banks, the apps.
