In a simple model where there was only one company that owned everything from top to bottom across the entire electrical grid from all power plants to every single power meter and everything in between? Yes I agree 100%.

However that's not how the grid actually works, so a simple understanding of the economics of a marginal turbine isn't the same as understanding the whole system.
