My advise: if voting is a distraction, then don't get distracted. It costs nothing. Cast it and care no more, focus on other things immediately after doing it. :)
You can't build a better future by just voting, but you can use it to stop someone from running your society totally into ground.
In my imagined future, a country can climb down from voting to sortition, and decentralize the power of sortitioned representatives further downward until the state is just a label, but abandoning the present because of a future that's out of reach - that's not wise.
The present system needs attending to, until the next step is within reach.
