You lost me on your post #54. I'm not sure what you are saying there.
Actually it's an application of common sense.
Government has no legitimate function except that it supposedly provides protection for the interests of individuals in conducting their relationships, businessness and/or personal.
When a government merely tells an individual what he, in isolation from others may do, that becomes arbitrary and tyranical as opposed to providing "protection" and equal "application" of law.
You cannot apply something (like taxes) "equally", in "common" or "general" without more than one person being involved. Read what article I Section 8 says is the purpose of the power of Congress to lay and collect taxes:
Constitution for the United States of America:
You cannot have debts without two or more persons involved, a debtor and and a lender.
You cannot have a "common" defense unless more than one person is involved.
You cannot provide for "general" welfare, where only an individual is involved.
All three cases involve the interrelationship among two and more persons, not individuals in isolation from others.
Look at all the enumerated powers of Congress, you will discover that they all depend upon activities of multiple persons for the concepts therein to have any meaning.
Law may be quite reasonably imposed upon single individuals as a consequence of their actions in regards others, it however becomes arbitrary and tyrannical when applied to one individual in the exclusion of others. Such laws that apply to an individual specifically without regard to others such as a "bill of attainder" is, for example expressly prohibited under Article I Section 9 of the Constitution.
The extension of that t applies to taxation in that the tax must exist for the purpose of generating revenues to provide for the execution of the Constitutional powers of Congress, (i.e.that which pays debts, provides for common defense, and general welfare.) All else is beyond the bounds of what a tax can be collected for, thus a tax to pay for "individual" benefit is not a proper tax under the Constitution; and law which applies to the individual in isolation from others is not a proper function of national government under the Constitution.
