Not quite. As per the post above, Article II, Section 28, still a provision of the Tennessee state Constitution states: "The Legislature shall have power to levy a tax upon incomes derived from stocks and bonds that are not taxed ad valorem."
The language in fact authorizes a certain tax- but not any other. And if the state constitution is renedered meaningless by abrogation and corruption of it as a consensual contract between governed and government, then it is NOT just the provision of Article II, Section 28 tghat is rendered moot and meaningless, but the entire constitution of the state, including those provisions that provide for a governor, or legislature, or judiciary. In that event the government of the state of Tennessee has no more legitimate moral or legal authority than any Memphis or Knoxville street gang, and will also then be afforded no more respect than they can compel and take by force.
When the government dictates the laws, it's a dictatorship.

The constitution expressly provides authorization to tax income from investments. By inferrence, if a tax on earned income isn't specifically authorized, it is forbidden.
