Yes dealing with domains, brands & property is challenging with DAOs.
Using a collateral system makes sense.
De-facto general partnerships may not be all that bad for DAOs as I wrote about here: https://steemit.com/eos/@steemrollin/nht3p-bitcoin-s-unit-of-account-the-watt
Anyways a lot of things to think about for those who want to create DAO dApps and protocols.
