Your suggestion is to merge them together?
I don't know if they can be merged, it depends on the intended use of boundaries.
Are boundaries only suppose to link to one circle?
SO can I create one boundary that allows all permissions to say circle named "Family"? Can I then create another boundary that is linked again to the same circle "Family", but then give it more restrictive permissions like the post can't be shared? Then if I want to share a post with "Family" I then have the option of allowing or not allowing them to share the post depending on the boundary I choose to use?
Circle I think makes sense. But due to social network nomenclature, maybe group or camp members would work better? If you want individuals to understand what they are using, similar verbs may be necessary for similar concepts. Otherwise, it can produce confusion regardless of the intention for simplicity or clarity.
here an attempt of an improved UI for boundaries, the main outcomes are:
