@deebee While I don't like not knowing how my representatives actually vote, I can see the reasoning for a secret ballot. The counter argument is that, come election time, the people have a referendum of sorts, and without actual performance information, the people are in the dark. I think the lobbying will continue, secret ballots or not.
And the reason is that government has too much power. And someone will want or need to control that power.
The point was that even if lobbying did continue, votes would not have to comply how the lobbyist wanted. The congress members could still lie and voted the way that the lobbyist wanted but really voted the other way
Though I think there could be a happy medium of finding a way to use crypto for voting, he also made excellent points as to why crypto could not be used on mobiles for voting.
