Bitcoin is thinking outside the box and libertarianism is inside the box. They simply can’t fathom another system entirely so they try to fix the problems within the system.
It just hasn’t clicked in their brain. It’s like the allegory of the cave. The propaganda is so deep they cannot even imagine another reality.
Bitcoin is a meme to them and not worth a second look. There’s also the fact they they would have to admit they were wrong in the first place about bitcoin which many are not willing to do. Libertarians think they have everything figured out. How ironic that they are stuck in the matrix as well.
