I think you missed the point. DAO and the funds they hold are not owned by anyone unlike Bitcoins who have a clear owner. I guess in some cases DAO can have a set amount of owners but this is not necessary.
Perhaps I'm misundertanding you but how exactly are the funds not clearly owned?
It's my understanding that each ethereum invested in the DOA still belongs to whoever invested them because they at any point can chose to split their funds from the original DOA into a different DOA where they then can extract the funds.
Returns on investments come back in the form of etheruem that will be evenly distributed to the DOA token holders meaning that even they will have a clear owner.
With that in mind I don't see how the fund are any less clearly owned by anyone than bitcoins, maybe you can explain?
