It doesn't surprise me that an anarcho-communist believes that dictatorships can be good to further the end goal of total equality through enforcement. After all, Karl Marx himself proposed that the Communist revolution would need dictatorships and conquests to facilitate the charging of norms, culture, and laws on the path to bringing all people to true communism.
I never liked that though. I mean, I thought Communism was supposed to be an inevitability according to a lot of Communists. So why do we need dictators? Won't Communism just be implemented anyway over time? Especially with the ideology's emphasis on conquest, conflict, and distrust, which provides a breeding ground for greedy, narcissistic, power hungry people like Stalin. I mean, for now can't we just use democracy? If implemented properly, it is the best system for preventing horrific famines, avoiding police states, avoiding unchecked, unstoppable corruption, and overall promoting good quality of life.
As for the Russian industrialization, that was achieved in part through forced relocation of the peasantry, which was extremely tiring and stressful for the peasants as well as causing a travel crisis as it became difficult to track who was going where (Stalin tended to impose relocations at seemingly random times). Conveniently, it also made it difficult for a resistance to form and unite as Russia is a big place, people were sometimes relocated more than once, and the population was being shuffled around a lot. While that may not have been the main reason for forced relocations, a paranoid guy like Stalin surely must have at least picked up on it. All that forced industrialization also left less people on hand to handle agriculture (not helping was that Soviet agricultural practices were terrible and not optional)-- and many of the large food-producing countries, especially the US, did not want to do business with Soviets. On top of that, the Soviet Union attempted to rival the US's dominance on agricultural exports, worsening the problem with famines since much of the food was going outside of the country. Soviet food had a reputation for being low quality and more expensive than usual so countries did not request imports unless they had no other options (like Cuba).
On top of that, the Soviet Union paid everybody in the same trade the same wage regardless of what they did for a living. A highly experienced, talented surgeon was paid as much as the surgeon who slept through medical school and only got a job because his dad's a politician for the CCCP. An efficient, passionate farmer was paid as much as the guy who's only working there because that's where he was told to go with the implication that he'd get disappeared if he didn't comply. As a result, there was little motivation for employees to do more than the minimum requirement-- assuming that said requirement was even truly met, given that it was common for supervisors to lie about their assigned area's output. And this caused the quality and production efficiency of Soviet goods to plummet.
