IRS admits guilt in a gross act of abuse of power

Perhaps the politicization of the IRS was inevitable. In any event, the agency is now completely out of control and has become an active threat to the integrity of our political system and the liberty and privacy of the American people. Our nation should move as expeditiously as possible to a different system of taxation for funding the federal government, one that does not create so many opportunities for the abuse of power. I do not have settled views as to which of the various alternatives would be most suitable; nor, I believe, do most Americans. It strikes me as time for a national debate on the subject. I would very much like to hear the strongest arguments for and against the different options.
