Incidentally, the Ran we are discussing is famous for holding that Dina Dmalchusa Dina is inapplicable in Eretz Yisroel. This teitch is not in dispute by anyone.
In fact, taxation is the primary component of Dina Dmalchusa. And the fact that a Jew is not obligated to pay taxes in Eretz Yisroel, clearly demonstrates Dina Dmalchusa is not binding in Eretz Yisroel.
This is aside from a whole host of other reasons that Jews are not bound to the laws of the illegitimate zionist regime in the holy land. (Without getting into the contentious specifics, i.e. the 3 shvuos, etc.)
