Fwiw, for anyone reading along, Chomsky didn't coin the term "state capitalism" and he was not the first to apply it to the USSR. Lenin himself actually uses the term to describe the USSR, seeing it as a necessary transitional step from (normal) capitalism to a socialist system:
"Reality tells us that state capitalism would be a step forward. If in a small space of time we could achieve state capitalism, that would be a victory."
And I'm of the opinion that the beginnings of the USSR, led by Lenin, were much more idealistic than what it would quickly become. Generally, it's the anarchists and libertarian sociliasts who are using the term disparagingly against a USSR that does not live up to their ideals. And, of course, Noam Chomksy is using the term "state capitalism" to describe a USSR that is much later in its history, or a USSR that is a thing of the past.
The Wikipedia article of the term State Capitalism is pretty interesting, imo: https://en.wikipedia.org/wiki/State_capitalism
