In recent times, Croatian political thinking pot has been enriched by new flavours - be it on mainstream or marginal scenes, nevertheless.
When it comes to mainstream actors that are attributed for contributing to this are mainly and probably mostly Živi Zid, a left-leaning populist political party that seems to find a way to capture the "angry" and "protesting" votes of Croatians, serving as an alternative to /age-old/ HDZ-SDP duopoly with whom people are obviously being fed up with.
However, on the outskirts of the political space, there is a notable amount of people amassing who believe in ideas of anarchy and not complying with (some of) the law of the sovereign state, or in this case - for these people - breaking the "agreement" with the state.
One Zadar resident particulary has been noted by the media in recent times who declared his "non-existence" to the state, therefore, not obliging to obligations which are backed by state, such as for an example registering a personal vehicle.
Interestingly enough, the state seems to be in state of confusion considering this case. The jurisdiction has not yet found an answer to this kind of statement, as shown by this example, by responding with a lack of official response. Meanwhile, the non-existing man is winning lawsuits against the police and "picking" which benefits of being in a state he will enjoy voluntarily, presenting an example of the state flaws to his fellow "living people", encouraging them to do the same.
This is a very interesting topic which seems to periodically stir up the imagination of public. Mainly because the legitimate existence of a state and its creation has always been questionable to reasonable men but also because of the many compulsory payments many Croatians seem to either do not want to pay for or do not have the money to pay.

For the questions of legitimacy of the state I suggest looking up voluntaryism and anarchy.
