I find the Mises Caucus at least useful in pushing to do more than simply be an affinity group for people pretending to play politics. I find partying with LP officials to be very hilarious, what a group of odd balls. But the party itself has no hope of electoral victory, which is why everyone should vote Republican in the current iteration of two-party politics from the libertarian lens.
I prefer corporations because I can voluntarily choose to take my business elsewhere, or even better, create my own competitor. Why I dislike the government is that it's the ultimate monopoly, with guns, and operated mostly by power-hungry sociopaths who will use that power to destroy innocent lives.
Given the corporation or the state, I take the corporation every time.
