I didn't know Mattick's introduction was on this site. Of course Mattick wanted a moneyless society (as did Kautsky and Bukharin). I mentioned him for what I read as his criticism of the phrase '... each according to their needs':
At this point, however, we encounter a difficulty and a weakness in calculating labor time, a difficulty which Marx had also taken into consideration, and, not discovering any other answer besides the abolition of calculation based on labor time for distribution, he put forth the communist principle “From each according to his abilities, to each according to his needs.”In his Critique of the Gotha Program of the German Social Democratic Party, Marx highlighted the fact that distribution in proportion to labor time would imply a new inequality, since the producers are characterized by different capacities for labor and by different personal situations. Some work more intensely in a given time period; some have families to maintain, while others do not; therefore, equality of distribution in accordance with labor time would cause inequality in the conditions of consumption. Marx writes that “In effect, with an equal amount of work contributed and therefore with equal access to the social consumption fund, one obtains more than another, one is wealthier than another, etc. . . . To prevent this unjust situation from arising, the law must be unequal rather than equal.” While he considered this inconvenience to be inevitable in the first phase of communist society, he did not consider it to be a communist principle. When the authors of the Fundamental Principles say that their presentation is “only the consistent application of Marxian thought”, this is true only insofar as that thought is applied to a phase of socialist development within which the principle of the exchange of equivalents still prevails, a principle which will come to an end in socialism.
Jules Guesde critiqued it as a pseudo-communist principle. You yourself admit that it's taken from Louis Blanc. And it's not because Marx speaks of a communist principle that it's beyond criticism.
Now you seemed to disagree with Kautsky's text, but now you (correctly) think it has nothing to do with parecon. If you read it close you'll see that Kautsky also wanted a moneyless society (like Bukharin), but it's how you get there which is the issue. If labour-money is still based on the principle of exchange of equivalents, then, like you say, why not keep using real money instead. You can criticize Lenin's two stage conception all you want and intend to communize everything from day one, but you have to admit that you can't jump right into communism, so do you agree with Kautsky and Bukharin that money will still exists in the first phase?

That Fundamental Principles of Communist Production and Distribution is really terrible, almost as bad as Parecon. As a blueprint for a labour-money economy it had already been criticised in advance by Marx in his writings against the advocates of labour-money (as an attempt to measure socially-necessary labour directly) of his day. No wonder Kautsky (who would of course been aware of Marx's criticisms) argued that, if you are going to go down that road (of accepting the terms of Mises's "economic calculation argument") you might as well use money and the market.
As to the slogan "from each according to their abilities, to each according to their needs" (which apparently you don't like), you are wrong. It was not coined by Saint Simon. His was more "from each according to their abilities, to each according to their deeds", ie what Stalin claimed happened in Russia and which both the Fundamental Principles and Parecon accept and indeed is the rationale behind piecework wage-labour. Its origin is generally attributed to Louis Blanc but was also used by Etienne Cabet. In any event it was current in the 1840s in Paris and it will be from the time he spent there then that Marx will have recalled when he wrote his notes on the Gotha programme some 30 years later.
I'm surprised you call in Mattick to refute it as "uncommunist" since in the very article he wrote in 1970 that you refer to he does say that today there is no point in tying consumption to work done but that society can go over to a system of free access according to needs,
As he says in the original German (since you refer to the German version) he writes:
Or, in English from this site:
So, I think Mattick can also be counted amongst those who want a moneyless society.
