Ah , so the lack of ambition in No Socialism isn't just due to the idea that 99% of the population wouldn't want to go further or EU regulations but actually is constrained by likely sanctions from countries that own business in our key services like energy, utilities, and transport if they were nationalised?
btw I'm not sure which model of French nationalisation you are referring to ;De Gaulle's post war wave of nationalisation, or Mitterands 'common programme' or perhaps you had in mind Macron's re- nationalisation of EDF?
