There is certainly a difference between "lawless" and "not MY laws" or "not the laws I prefer". In my view the parent comment is framing the situation in an incorrect or at least incomplete way. The residents of Liberland were not conducting activities that would be considered obviously criminal by most societies. And I don't know the details of their legal system but "complete anarchy" seems unlikely.
The Darien gap, China & Myanmar border region, central Africa -- these are "lawless" areas despite having clear territorial ownership.
