I recall a few years ago a couple built a home on international waters, near Thailand, and was simply taken out by the Thai government. Without nominal security, or any organization to avail them, that's the last time I heard of them.
Liberland may have some relationships solitary households do not that can avail folks some security from violence, by gangs of thugs from any source. Some security obviously is necessary, because it is all too obvious predatory entities exist.
I haven't spoken with Vít Jedlička since 2018, so I'm not sure about the current status of Liberland.
As of 2018, Croatian forces were routinely and forcibly evicting or detaining any Liberland citizens trying to visit their 'homeland'.
The information I was availed most recently was of the opening of Liberland offices in Mexico after Anarchapulco, from Jeff Berwick's vlog. More than that I do not know.
