Everything you said should be enough to get people to vote, but the sad reality is reducing it to that may not be enough.

I understand why it isn't enough for a lot of people. I think the biggest reason people don't vote is they don't feel their vote matters all that much, and/or they see a certain futility in the whole thing. I understand why, in the face of that apparent futility, many people feel powerless and thus choose to disengage. But, yes, as you've said, disengagement does nothing and the only way to take back power is greater engagement. The powerful want us to feel powerless, they want us to be disengaged and they want us to be misinformed, thus we gain power by being informed and engaged, which will lead to us feeling empowered, which promotes even greater engagement.
