Her video is a perfect example of somebody having a lot of expertise in one domain and making the mistake of thinking that it's easily transferable to a different domain. She falls into many common traps such as using no true Scotsman fallacy to defend capitalism, brushes off places like Cuba and DPRK without considering the context, and completely ignores the exploitation inherent in the capitalist system. She also appears to conflate markets with capitalism, and doesn't even bother considering whether useful aspects of capitalism could be applied within a different framework.
Overall, it was a very superficial and disappointing video from her that immediately made me question things she talks about on subjects I'm not well versed in.
