Nah, it pretty much is, for anyone wanting to continue living in a United States. Even tax cut libertarians should recognize that the least just taxation system is random, which is what you are essentially advocating. Moreover, unplanned income drops are a huge problem for government finance, and by extension, corporate finance. A competent government produces a budget, a tax schedule, and raises debt to meet any planned deficits.

Constitutionally, the House holds the purse strings, not the Supreme Court, and overturning 200 years of precedent here is not in anybody's best interest.
