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.
The government as it is the world over pretty much controls your entire life; It dictates what you can and can't do with your own body, it forces you into various forms of indentured servitude, it marks you and keeps track of you like an inventory item, it controls what you can say (where and with whom even), it takes your children from you and puts them into essentially indoctrination camps for "education", it comes up with arbitrary rules that you have to jump through hoops to abide by, and it can even take your children away if you don't teach them the approved things, it can take arbitrary control over any and all of your possessions for whatever reason, it orders you to harm your fellow man, etc... And most of all, it gaslights and forces you to go against your own morals or things you consider wrong, whatever that may be. And just to rub it all in? It says you have to do and abide by all these things whilst still loving government because it's "Democracy" and "Democracy" is pure and noble and fair.
