those who advocate for land value tax are usually advocating for single/minimal types of taxes (and, in fact, against sales and income taxes) rather than a cocktail of them. "Single Tax" predominantly refers to a single land value tax. https://en.wikipedia.org/wiki/Single_tax

My point is that a single land value tax would have the same effect as piecemeal improvements to current tax portfolio - none of it would fix the inertia already priced and baked into the system.
