Granted, we may be motivated by respect for another's rights, but that's not what I mean. Rather, I wonder whether having a right to do something can sensibly be described as one's motivating reason for action. I recently read a survey which asked local voters for the reason why they voted. Many cited "democratic duty", or the desire to "have their say", either of which seem perfectly comprehensible reasons. But then others cited their democratic right to vote -- which just seems bizarre.
As I understand it, a "right" in this context simply serves to guarantee that an option remains open to you, in case you wish to take it. Some independent motivation is required for actually bothering to claim the right, however. It's as if these voters were to explain their walking through a door by citing the fact that it was open. It's really not a very illuminating explanation of their behaviour. (Was there something they wanted on the other side? Were they just curious?) "Because I can" doesn't sound like a very sensible reason for anything much at all.
Am I missing something here? Care to hazard a guess at what the survey respondents may have had in mind?
