How bitcoiners should argue big state believers? Don't.
I used to be that guy. Long before I was into bitcoin. If they aren't open it doesn't work. It is religious. At best you can drop seeds. Now if you are debating a statist with the goal of educating those that are on the sidelines then yeah I can see the value.
Sounds like you are basically trying to decide between the utilitarian vs moral approach. I'd say it depends on the person. I don't think there is one that is better than the other.
