At what point do we no longer have to obey the government?

I would like to start a fundamental issue discussion on this question:
Is there a point where we no longer have a moral duty to the Federal
and to a lesser extent the State governments as a citizen of the
United States?

I will place as my point of this end of duty a simple one. Its no
longer a viable and legal government when the Federal authority
violates the core authority limits in the Constitution and is
therefore acting against the limits of the highest law of the land. I
would place it here because no authority can be above the highest laws
of the land, no president and no member of the Congress can violate
that and no judge do so not without losing their credibility.

In my estimation the current government under this standard is no
longer meeting the moral and legal authority to demand I be loyal to
the Federal Government and is a de facto illegal government. Just the
fact it ignores limits afforded to it and it has far exceeded the
powers confined to the Constitution proves that enough such as the
illegal and long term standing Army as just one example and the
destruction of States Rights at fundamental levels. I for one feel
more loyalty to my State and local governments over the Federal one
and that is sad for me personally to love my country but not the
government that leads it but for me they have gone to far to give them
my allegiance.
