It seems like you've already answered your own question, except I'm not sure it's typically called "symbiosis". The term is usually used in biological contexts; I think you're interested in more basically the idea of a social contract where you agree to give up certain freedoms for greater security in society.
So, is there such a thing as enforced symbiosis?
Well, technically yes, but I'm not sure it's called that.
You also mention:
I'm simply asking if enforced symbiosis is still considered a
Well, to answer that: I'm not sure there is such a thing as unenforced symbiosis (when it comes to the human-based, "political" symbiosis you are referring to). To enforce means to compel obedience to, to impose, and virtually all social contracts are enforced via laws/rules/a moral code and some enforcing agency, whether that be the police, some particular leader's gang, or even mob rule (i.e. the rest of society). Thus, most cases of "symbiosis" in the sense you speak of is forced, although theoretically it doesn't have to be (and in terms of biology, it is almost never enforced).
