Feeling deeply dissatisfied with living in a statist society, a rather broad group of anarcho-capitalist types seek to set up their own country. They manage to get some wealthy backers, who may wish to see such an experiment crried out for their own purposes and/or who may actually believe in the ideology. At the same time, the Philippines end up in some kind of unfortunate situation (possibly involving an extrapolation of current politics there, since those are... not great) that leads to economic disaster. In highly capitalist manner, the anarcho-capitalist group eventually buys certain parts of the Philippines, to set up their own state.
Shortly thereafter, as they are setting up their "private law society" (or whatever they end up calling it), the Hoppean faction gains overwhelming influence. Perhaps they are simply a majority among the first ones to immigrate? It depends a lot on what this "Federation of Sovereign Voluntarists" actually
is. How is it structured? If it is
actually anarcho-capitalist, getting any ideological group 'in charge' will be difficult. I've outlined some ideas on how such a societies could go right or wrong
over here. Besides the value one puts on either equality or liberty (which largely decides whether one considers such a system to be
inherently superior or inferior to a more statist, distributive system), the main way I can see such a system go 'evil' is through a concentration of informal, economic power in the hands of a small elite.
An attempt to enforce one particular ideology is by definition difficult. It can be done if said elite is fully dedicated to that ideology, but otherwise, it basically requires that the anarchism gets diluted and a state apparatus is set up to enforce said ideology. The only other alternative I can see is one whereby the country is founded and populated
exclusively by Hoppeans, but I doubt there are enough of them on Earth - let alone enough willing to move to a new country - to set up a breakaway society.
Essentially: if the "Federation of Sovereign Voluntarists" is truly a stateless venture, then you will either have to make it so that the land where it's founded is bought and owned by a bunch of very rich, very dedicated Hoppeans (do any wealthy Hoppeans even exist?), or so that a group comprised exclusively of Hoppeans settles there.
(A potential outcome would be a mix of the above. A group of anarcho-capitalists essentially buys a country, which is carved out of territory formerly belonging to the Phillipines. They have a number of wealthy backers, one or two of whom would be a dedicated Hoppean. This results in a part of the new country being owned by this rich Hoppean investor, who onlty sells or rents part of his personal land to fellow Hoppeans. So you get a Hoppean sub-section within a broader anarcho-capitalist society. Fairly soon, the Hoppean part closes itself off completely to all non-Hoppeans, and secedes from the rest. Take it from there.)
