I will bring this up every time someone mentions this, but your money is not being taken without consent. You are signing tax forms without knowing what they mean in law and voluntarily (incorrectly) giving it to them. Income taxes are excise taxes.

You can migrate and renounce citizenship. Staying and benefiting from the spending is tacit consent no?

taken without consent; every constituent who voted for every representative who ratified the 16th amendment is now dead

Isn't it nice when you get nerd sniped by complete nonsense? I wanted to see what amendments would get invalidated using the quoted line of reasoning, aside from the whole Bill of Rights. Using the date of ratification from Wikipedia and subtracting the voting age at the time gives you the absolute lower limit of the age of any voting constituent:

Using the SSA cutoff date of 115 years, we see that the 20th and the 21st are a bit iffy, which isn't so bad because the 21st is the repeal of the 18th, and the 20th is a bit technical, but: women's suffrage is kaput! Slavery is OK again! Senators are to be appointed! Etc. At least term limits still apply, whew.
