They experimented, and they discovered what happens if you try to claim land that isn't yours. They also discovered what happens in a libertarian world when someone stronger than you wants your stuff.
No it doesn't. You're projecting your own value, interpretation and criticism of libertarian concepts to make it mean "dominance of the strongest". It's no more the case than with all other forms of government, including the majestic and noble "democracy".
Sure, it depends on the disposition of the polities around you and how strong the police/defense force is. You could also run it with any system of government you like, libertarian or otherwise.
A lot of people in this thread are laughing at the Liberland folks for being doomed to fail, not realizing that "might makes right", etc. Well how would we be reacting if they became terrorists instead? Defended the area with homemade bombs? What if Jeff Bezos built a private army and decided to secede from the US?
The morality or intellectual interest of a people's claim to a territory (along with their chosen system of government) is completely orthogonal to their ability to enforce it. For the other end of the spectrum just look at Ukraine, as others here have pointed out.
Ukraine situation is a conflict between two states. International world is a libertarian world. The whole point of having countries is that a country can offer something better to people within its borders. This is achieved through monopoly on violence. Internationally, there is no monopoly on violence; arguably, the only thing keeping the world mostly together is nukes.
I've seen quite a few libertarians that would argue for private enforcement of property rights, thereby abolishing the need for a government altogether.
So if I pay a bunch of guys to enforce "my property rights" over their house, then it is my house right? So now I'll force them to pay rent for it or my private thugs will evict them from "my home".
Is that what they want? That is how society worked before we had modern governments. The only way to prevent this is to have a government who tells me I can't just bring a bunch of thugs and take stuff from people.
Undoubtedly, but those aren't real libertarians. They're anarchists.
Libertarianism is a free market economy, with the government serving as enforcer of property rights and contracts. The government also enforces individual rights.
Such as the rights to life, liberty, and the pursuit of happiness.
Yes, there always tends to be a large number of hypocrites in the world, see any socialist or communist of modern times who are all talk but take on none of the risks by living their ideals.
Well, its about claiming land that the Croatian government doesn't even claim to own.
Ironically, the fact that the Croatian government kicked them out, harms the Croatian government's legal claims with Serbia.
