This is going to turn out to be important the first time a DAO gets significantly scammed. Someone's going to take the money and run, or otherwise violate the "contract" that the DAO thought it was "enforcing", and... there won't be anything to do. There won't be any way to fix it. The smart contract doesn't handle the edge case of having to hire a lawyer on its own behalf.
I mean, just to take this particular mostly-harmless situation as an example: that membership in the Blender Development Fund presumably includes some amount of official input into how the money gets spent. What if the DAO has specific desires or expectations, and Blender simply chooses to ignore them?
