No, it's as silly as suggesting that a single voter has any say what so ever in the policies of republican institutions.

1 vote for a poor person = 1 vote for a rich person (ideally). In mining, the more mining power you have, the more "say" you have. One stays constant, the other scales. Don't you think that is an important distinction?

In a way it's a pretty naive view. The rich person will have more influence over other people that will give him effectively more than 1 vote.

OP's point is the big mining rig will have more influence than the numpty rig one boots up on their laptop.

Sure, each has one vote.

But it's not your one vote that makes any difference, It's how many votes you can influence. And that's all about privilege and money. Campaign funding. Lobbying.
