Australia will run an overt command economy by 2040

> In other words, the economy is producing gross shortages and excesses of many goods because government interference in natural pricing mechanisms is so excessive that information transfer through prices no longer exists in a functional way. This is clear in the case of housing, education, healthcare, and now fuel, but also occurs almost invisibly in nearly every other economic edge node that Australians routinely use.

From the first sentence:

taxation past the Laffer curve’s point of peak growth,

The Laffer curve doesn't have fixed parameters. You can only tell the peak by experiment.

The Laffer curve only tells you that the optimal taxation point is not 0% or 100%, which you don't need an economist to tell you. And even that is just a trivial model, with the boundaries fixed by assertion rather than measurement. A model with more variables might well have nonzero revenue at 0% and 100%.

A few paragraphs in he misunderstands the word "Communism" -- which is a common enough mistake, and the definition is very fluid, but if you're going to appeal to numerical values you're going to have to do better than an ideologue's misunderstanding of economic terminology.
