Judicial supremacy is a myth under the text of the Constitution and it is just as much a myth as the income tax being unconstutional. Juries are allowed to rule on the Constitution under the ninth amendment as this is called jury nullification which is an American tradition dating back to the Magna Carta. The Supreme Court might say that there is no jury nullfication under the Bill of Rights and might instruct jurors to rule on only guilt and innocence but this act by the Supreme Court is unconstitutional and so jurors must rule to nullify the Supreme Court with the use of jury nullification.
Also Congress doesn't have to fund the Supreme Court and also Congress can control the jurisidiction of the Supreme Court. Congress has abused this power by enacting laws that sanction "tax protestors" so it isn't like the government wins fair and square.
LAst, the preamble to the Bill of Rights says "In order to prevent the misconstruction and abuse of powers, further restrictive clauses must be added" and thus the bill of rights restricts taxing, spending, and judical power esp the ninth amendment even if the government denies it.
You don't even have an argument here. You're just saying "it's unconstitutional because I say it is". Judges are members of the legal profession and serve as experts in what the law says - that's why they act as interpreters in a court of law, and evaluate legal arguments. It is really, really telling that no judge or bar association has ever said that the income tax is an unconstitutional tax - instead, they have repeatedly found that it is a constitutional tax, and the current one was explicitly allowed for in the 16th amendment. That was
why the 16th amendment was passed.
Jury nullification occurs when a jury acknowledges a law, but disregards it for what they feel are more compelling reasons. This has absolutely nothing to do with constitutionality - if the income tax was unconstitutional, juries
should rule against it, and would not nullify anything. What you are arguing is that juries should disregard the opinion of
every single legal authority and instead say the constitution says something which it explicitly does not.
Hell, why we're at that why don't we just throw atheists in prison and then make specious legal arguments that it's okay because atheism isn't a religion under the free exercise clause, and then use jury nullification to uphold it. Jury nullification isn't a magic ticket where you get to write in whatever rights or lack-thereof you feel like filling in; and this falls right into that category. For someone who purportedly really cares about the Constitution and the set of checks and balances it laid out, you appear to basically be willing to say "SOD OFF" to the judicial branch when it tries to enforce a law which Congress amended the Constitution to allow because you don't like it.
Think about that - Congress, following the principles in the Constitution, amended the Constitution to explicitly allow for a non-apportioned income tax. This was ratified by the states, and both houses. The judiciary, acting as an arbiter of laws, correctly interpreted the amendment to allow for an income tax, and upheld the subsequent laws Congress passed following the 16th amendment. The will of the people, reflected in both Congress and the states passed a law you don't like. Your response? "Screw them all, we should just ignore it. And we should remove funding from any judge who applies the Constitution as it is written".
That's not the rule of law, and that's not respecting the Constitution. That's throwing a petulant little fit, and a tremendously shortsighted one at that. I am reminded of a famous quote which you might want to reflect on:
Accused by his son-in-law, Will Roper, of giving the devil the benefit of law, More retorts: “What would you do? Cut a great road through the law to get after the devil?”
Roper, also a lawyer, is quick with his answer: “Yes, I’d cut down every law in England to do that.”
“Oh?” says More, “And when the last law was down and the devil turned round on you, where would you hide, Roper, the laws all being flat? This country is planted thick with laws, from coast to coast, man’s laws not God’s, and if you cut them down—and you’re just the man to do it—do you really think you could stand upright in the winds that would blow then? Yes, I’d give the devil the benefit of law for my own safety’s sake.”
