Ooo man, this is a super underrated take. Too often people get caught up in what the law is trying to do, how people could get around it, and what the incentives/disincentives are, while not really taking into consideration how the law would actually operate. Sometimes people get all conspiratorial about it trying to point to ulterior motives, but man, most of the time it’s more that bad-faith actors are taking advantage of what’s already out there rather than actively creating the problems they want to create.
Eh, I dunno that I’d actually characterize him as a liberal so much as him being an authoritarian that just pushed whatever happened to serve him at any point. Kinda in the same vein of fascists not having any economic ideology, just whatever serves their ideal of the state at any given moment. So yeah, I certainly agree with your sentiment that Stalin certainly was not a communist, but more because he only cared about gaining/maintaining power rather than actually subscribing to any economic theory.
