Income tax not slavery. The government has created all the money (the only thing they do actually make) and has a monopoly on its use. They have a right to charge you to use their currency. Income tax is but charging you a fee (paid in their money) for the right to use their currency as a means exchange.

Government did not make the land and they have no right to claim to own it all with property tax. Income tax does not force you into debt only property tax does. Property tax forces you to make money for the state. Property tax FORCES you into government servitude in order to keep your home. Income tax doesn’t keep you from making money. It only means you make less. You aren’t working for the government you are simply being paid less for your work. If you don’t like what the government takes you need to work for something other than money.

Slavery only occurs with income tax when you are forced to file your tax return. Even if government compensates you for your labor it is paid with their money and you were still threatened with the loss of what belongs to you (your liberty and property) if you do not file your return.
Perhaps the greatest lie ever told is the American Dream of home ownership as property tax clearly prohibits ownership making it impossible to ever become free from debt. Property tax is the evolution of serfdom where kings and lords have been replaced by rulers of the State. This medieval extortion, collected on unrealized capital gains, makes the peoples homes into investments of the State. Property tax forces the people into government servitude in order to keep their homes. Clearly as in the past, modern day serfdom is intended to prevent the people from ever acquiring liberty. With property tax the people must pay with government currency. Gone are the good old days when you could pay with chickens, some other farm product or manual labor

Home ownership is in fact the greatest lie ever told. It’s ludicrous to say you support property tax because property “owners” benefit from government protection when property tax makes government the owner. Government is the one that will throw you out of your home if you don’t pay them and they are the greatest threat to the security of your home. Property tax makes government into a criminal syndicate collecting extortion. With property tax government is denying the people the essence of what it is supposed to protect.

The ability to “own” property is the source of freedom. What ever stored wealth property represents is worthless when it negates this principle. Do you believe government has the right to put a price on liberty? Being forced to pay another to keep what belongs to you is slavery and this is precisely what property tax does.
Property tax is slavery.

Property tax prohibits the ownership of property. Property tax forces you into government SERVITUDE in order to keep your home and redefines “ownership” as being that which is only allowed if you’re continually wealthy. Property tax prohibits the poor from having anything and separates society into a cast system making it impossible for the poor to have land.
Property tax forces you to WORSHIP the government with the almighty dollar and is only tax that FORCES you into eternal debt and makes the acquisition of liberty impossible. Property tax is pure evil

Your analysis, while relevant for current court proceedings, seems to conclude that a progressive income tax, as suggested in the 16th, is a good thing only because adam smith and “every modern democracy has one.” Huh? Let’s see, if every modern “democracy” (thought we were a “republic”?) goes for state run Health Care, and at least one book author and theorist support it, then it must be a good thing, right?

You may have proven a legal technicality in your observations, but you really have some work to do to build your case that taxation, as administrated currently, is moral, was intended by the founders, and has anything at all to do with Liberty.

It makes you appreciate that our “Founding Fathers” weren’t exactly the infallible gods we sometimes make them out to be.

Websites and books that post the U.S. Constitution will often italicize this kind of meaningless text that remains, and the language you cite from Article 1, sec. 9 is indeed obsolete:

Given that Article 1 lets Congress “lay and collect Taxes,” and that the 16th Amendment expressly allows Congress to tax incomes, you’re arguments are hopeless, from a legal standpoint.

Is the federal income tax a wise or moral policy? You can still make the argument here, but there is absolutely no question that the federal income tax is constitutional. Of course, Adam Smith himself supported a progressive income tax, and every modern democracy has one…
