Regardless, the Israeli government does not hold of the Ran or ANYONE else for that matter. So there is really no point discussing halacha when the government will not abide by it.
Correct me if I’m wrong, I believe the initial discussion of dd”d started in response to this statement of yours:
If you voluntary live there, please follow the law.
Nobody thinks the government cares if we pasken like the Ran or the Rambam (or whether the Rambam would apply to a secular government), you addressed the frum people living there.
