My only objections are if the conduct used to receive the early vaccine was unethical, it involved diversion of doses away from higher priority recipients, or an example like that Canadian casino owner who flew into a small town in the Yukon so that he and his wife could get an early shot.
I have no objection, though, to someone using their time and resources to scrounge for left-over doses. Even though this might favor those from more affluent demographics, the end result of less community COVID vulnerability and doses not being wasted is only positive.
