Well we can easily look back and demur, but what needs to be remembered is that there was no such thing as the internet.
I myself find it hard to imagine such a situation. The paradigm shifted, he didn’t. No doubt he altered his rhetoric, but I don’t blame him for that.
It was write with the anti-war, anti-state crowd or really not get published at all. He did try to form allies for sure - but I see it as great that he did.
Rothbard tried and it didn’t work. Seriously - if he can’t do it, no-one can.
Granted he did learn the lessons himself though;
What We Mean by Decentralization - Rockwell
Rothbard himself, in the course of experience, changed his view on the best method for organizing ideological movements. Early on, he was attracted to the idea of top-down management, with cadres and followers and cells of every sort. He saw that this worked for the Communists, so why not for the libertarians? He was right to say that nothing in libertarian theory prohibits top-down management insofar as it is voluntary and rooted in private property.
But later on in life, he changed his mind and wrote that he found serious problems with this model, and they are related to the same problems that appear with political centralization. In the Libertarian Forum, August 1981, he writes:
“I would like to take this opportunity to admit my previous error in calling for an ultra-centralist model for the [Libertarian Party]. Several years in the [LP] have soured me on centralism permanently. Putting the rule of the Party, or of the movement as a whole, into the hands of one man or of one tight group is a recipe for disaster. First, it means that if a few people sell out to opportunism, the rest of the movement is dragged along with it. But second, and more generally, even if the Machiners were a bunch of wonderful people, since they are not omniscient they are bound, as are all of us to make mistakes. And just as the mistakes of a government-controlled economy can ruin a nation, so the inevitable mistakes of a tight ruling clique can ruin a party or a movement. I still think it absurd to think of decentralism as ‘the libertarian’ form of organization. How we organize is not a matter of libertarian principle, so long as we do not violate the non-aggression axiom. But it appears that neither radical decentralism nor ultra-centralism will work in any organization…. [M]oderation and balance should be our organizational mode.”
