When I say here, I mean the gemara in nedarim. Apparently you are saying there are two theories of dina d’malchusah, and neither apply to the gemara’s case, but the ?? only explained why one of them does not apply.
As far as the shutfus theory, I respectfully disagree. I do not think there is a shutfus theory that works in democracy, since nobody in the country views it as a shutfus; everyone views it as struggle to get the most value for themselves, including risk aversion, satisfaction of belonging to a social welfare state, and other satisfactions.
