To put it differently, just because there are no consequences to one person acting in a certain way, it does not logically follow that there are no consequences if a significant number of people act that certain way.
Who says that it follows? You just made a straw man. No one argued that there are no consequences if a significant number of people act that certain way. Of course if everyone stopped voting then things would be different.
But people DO vote. A hundred million people vote. I live in a red state. Voting for president is a complete waste of time for me. My state will go for Romney this fall no matter what I do. If enough people stop voting then maybe I'll think about it, but from a logical perspective there is no reason that any individual should waste their time voting. It won't make a difference. At best it can make someone feel good, but since I don't buy into any of that "people died for your right to vote" or "it's the one day you have as much power as anyone" nonsense I'll find something productive to do instead.
