One can define new concepts by creating a vocabulary. Please see example in AS2.0 Core http://www.w3.org/TR/2015/WD-activitystreams-core-20150129/#fig-an-object-that-is-both-a-place-and-a-gr-location

namespacing doesn't matter if everyone agrees on one vocab right, like mf2 or schema.org - but as soon as someone wants to coin their own term in a decentralised way (maybe if they want to expand AS2 with a new content type) and describe it, the documentation for that should be some way discoverable, which is why namespacing is useful, JSON-LD or otherwise... as I understand, anyway
