Nah, their argument is clearly an analogy between both situations, to “prove” both things are the same.

That said your concern is reasonable. It’s about transition; something the left has been discussing since at least the Second International. Individual takes go from “you won’t make an omelette if you don’t break some eggs” to “minimise harm as much as possible”. I lean towards the later - seize, put it under the control of the workers and/or general population, let them gradually restructure it, repeat as needed.
