Different systems for different people. There is room for monarchies, a natural human order system, and room for libertarian free states. Not everyone, every family, tribe or culture views their system as slavery. Some view it as an extention of their genetic and cultural family. The American style revolution replaces monarchy with celebrity, god with money and family with media. The french and chinese although very different replace monarchy with the state, an artificial creation. We should have one or a few free states, libertarian, voluntarist , whatever. Like Bitcoin they provide an alternative if abuses go too far in other state structures as they cycle through various factors such as economy and population age. I appreciate where you are coming from, but its short sighted in regards human behavior, needs and inter human relationships. A subject of a monarchy is not a slave, but they are not "completely free", neither is an american, and less and less so. I can point to several people in prison and actually persecuted in sipposed free countries for every one "under investigation". But they were more free. Following your same arguments even americans, who must always pay property/land tax, subject to the draft, and all sorts of other things, are slaves. I know this sounds statist, but in light of the fact your alternatives have yet to proven to work for millions of people and be a better alternative (slavery is allowed under some libertarian visions) i can be "anti" statist and also acknowledge it could be much worst, that monarchy and democratic states have some good features, and i can then also further claim that a non-violent transition to a better one would be good, without contradiction. Your post calls for violence, which itself would lead to an NAP violation of people who enjoy monarchy. Have you considered that under libertarian principals the king is just a large inter generational property owner? Property Rights as you conceive them did not exist before terra nullus, for instance. All property rights also derive from the ability to enforce them, thus for americans this transferred from the king to the state system and minor kings, presidents. Someone had yo claim all lamd, to then be able to parcel it out. How could it be otherwise ? All the while these minor kings maintained slaves , while the monarchy actively abolisged them, for capitalist reasons by the way, not just humanitarian. You need to read more history, the violent stuff. Touch more grass and travel more, meet people and live in other countries. OP can pay a fine, others can continue work on it, the community can learn the dumb and obvious lesson that releasing potentialy controvertial software under your real i.d and without opsec is dumb and obvious, by now. They can move, work on new things. But killing monarchs instead of slowly making them irrelevant and symbolic, is burning down the house to kill a mouse. Cypherpunks write code. They don't kill or fed post.
I was pointing out that there is no non-violent transition. Hence, I'm not a libertarian. No matter the system, if your family, tribe or culture finds it destructive, you must replace it, violently. This is nature's law. Without any rights to fix it non-violently, violence is your only right. Yes, Americans are also slaves. If the slaves wants a change, they have to physically annihilate the entire nomenklatura of the United States, from top to bottom. This is their only right. You can't hide from Judeo-Bolshevism. They will knock on your door. This must be accepted. If some of the Brits wants a real change, they must physically remove the Royal Family and the entire Marxist state apparatus beneath. This is their only right. This is OK in nature. That's how it operates. Act accordingly. Revolution is the only solution.
And then what? The day after the revolution, after the blood has dried, buildings burnt, food, electricity, systems cut.
