Rights don't automatically mean "free" economically.  What it means is you are "free" to vote and for anyone or anything on the ballot!  When the "frugal" people who end up short at the end of the month go to the store, they can drop off their ballot at drop box or on their way to work and back.  

You can either see it as your duty to vote and a privilege or not.  The choice is "free" and up to you.
