Copyright is an exclusive right to reproduce a work in order to inspire the creation of works. It is not a moral right to control others communications.
The reasons it is nonsense to own exclusive right to a title
-It hamstrings communication about the work including both criticism and the ordinary business of civilization where we communicate things that we have learned with one another. The title is the only proper referent.
-It never stands in for the work itself unless the work is itself so trivial as to be not worth protection. For example [insert name] died that is all.
There is no reason to suppose one ought to be able to opt in or out of being shared on Facebook than one could opt in or out of being shared in an email or in a coffee shop.
Can you imagine going into starbucks and seeing a list of authors whose works were licensed to be discussed there.
A lot of people confuse there being a handle somewhere with the right to grasp it. Facebook being at a central point in many people's communication could pay the parties being discussed, so could your email provider, or your cellphone carrier.
Any of the above could allow parties to censor your communications at the behest of others like you suggested.
The fact that copyright is so adaptable as to readily be twisted into such ridiculous ideas is a good argument for throwing the whole thing in the trash.
