That's a dumb thing to say, because it sounds like striking worked in this situation. By this same all-caps libertarian logic, any strikes would be ineffective

That's a dumb thing to say, because it sounds like striking worked in this situation. By this same all-caps libertarian logic, any strikes would be ineffective because the workers need "The FACTORY" or whatever. The "university" is a huge collection of thousands of people, numerous competing groups, etc. The grad students can shut the whole thing down if they strike, because they are integral towards research and undergrad education happening. There's nothing quite like the unfounded confidence that ignorance brings.
