Science is defined by material and formal consistency. If a theory/model fails on one criterion it is scientifically worthless. With regard to formal consistency, there is no way around “... he who contradicts himself proves nothing” (Klant, 1988, p. 113). But formal consistency alone also proves nothing.
The actual state of economics is this: Orthodoxy has failed on both counts. Therefore, all hopes rest on Heterodoxy. The crucial question is, does Heterodoxy satisfy the indispensable methodological criteria? Let us have a look at profit theory.
The profit theories of Keynes, Kalecki, Minsky, Keen are different (Marx, Mises/Hayek, and others could be added). They cannot all be correct at the same time. As there is only one Law of the Lever, there can be only one objective Profit Law for the economy as a whole. This is not the case.
(i) Keynes: “His Collected Writings show that he wrestled to solve the Profit Puzzle up till the semi-final versions of his GT but in the end he gave up and discarded the draft chapter dealing with it.” (Tómasson et al., 2010, pp. 12-13, 16)
(ii) “Kalecki derived this relationship in an extremely concise, elegant and intuitive way. He starts by making simplifications which he later progressively eliminates. These assumptions are:
• Divide the whole economy into two groups: workers, who earn only wages and capitalists, who earn only profits.
• Workers do not save.
• The economy is closed (there is no international trade) and there is no public sector.
With these assumptions Kalecki derives the following accounting identity:
where P is the volume of gross profits (profits plus depreciation), W is the volume of total wages, Cp is capitalists consumption, Cw is workers consumption and I is the gross investment that has been made in the economy. Since we have supposed workers who do not save (that is, to say in the preceding equation), we can simplify the two terms and arrive at:
This is the famous profits equation, which says that profits are equal to the sum of investment and capitalist’s consumption.” (Wikipedia: Kalecki, 2015)
(iii) Minsky: “The simple equation 'profit equals investment' is the fundamental relation for a macroeconomics that aims to determine the behavior through time of a capitalist economy with a sophisticated, complex financial structure.” (2008, p. 161)
(iv) Keen: “Total income = Wages plus Profits” (2011, pp. 366, 146) and “... national income resolves itself into wages and profits” (2010, p. 12).
It is quite obvious that heterodox economists, like their orthodox counterparts, have NO idea of what profit is (2014). Hence, they fail to capture the essence of the market economy. Because of this, economists have nothing to offer in the way of a scientifically founded advice.
“In order to tell the politicians and practitioners something about causes and best means, the economist needs the true theory or else he has not much more to offer than educated common sense or his personal opinion.” (Stigum, 1991, p. 30)
The true theory satisfies the criteria of material/formal consistency. All that Orthodoxy and Heterodoxy have currently to offer are contradicting opinions; neither came ever to grips with science, with profit and with the working of the economy we happen to live in.

You say: “The approach, I think, is simply to determine that economics is a defunct discipline like alchemy.”
The problem with incompetent folks and mainstream basher like Lars Syll and you is that traditional Heterodoxy has failed since 140+ years to develop a suitable alternative to the maximization-and-equilibrium phantasm: “... we may say that ... the omnipresence of a certain point of view is not a sign of excellence or an indication that the truth or part of the truth has at last been found. It is, rather, the indication of a failure of reason to find suitable alternatives which might be used to transcend an accidental intermediate stage of our knowledge.” (Feyerabend)
As Nell put it: “As will become evident, there is more agreement on the defects of orthodox theory than there is on what theory is to replace it: but all agreed that the point of the criticism is to clear the ground for construction.”
Neither Lars Syll nor you have ever constructed anything of scientific value.#1, #2, #3
