@nima this is fantastic and brings vivid clarity to the question! This dialog has also helped us bring ultimate clarity to the definition of a Guild too, which is amazing.
What’s great is there generally seems to be consensus here. 
Let’s see if I can summarize the feedback so far:
A Guild is a group or groups of people that unite under a topic, cause, or region within the NEARVerse. It’s a way to organize specific skills and interests and give them a home.
A DAO is an on-chain DApp that provides governance for a specific topic, cause, or region through community proposals and voting by an approved board.
A Guild with multiple DAO’s makes sense with meta-guilds, guilds that have grown beyond the threshold of governance, or for a specific sub-topic or project.
With the clarification provided by the community Guilds and DAO’s serve distinctly different purposes and functions that complement one another in the NearVerse.
Having the DAO a top-level topic makes sense for promoting that this is a core piece of the ecosystem, however, each guild’s DAO(s) may not be of interest to everyone and it could get messy. It sounds like a happy medium is to have meta-guild level DAO’s at the top level and guild specific DAO’s as sub-topics of guilds.
