i dont think so, it all depends what do we lose as a result of that monopoly ( lost value creation, higher prices, less innovation) and the type of monopoly would be a factor in that consideration ( a state monopoly has externalities a natural monopoly does not) , so depends on the industry, type of monopoly. i think monopolies are kinda necessary evils to make other markets work effectively in certain areas of an economy ( ie utilities-esque services ) but id love to know of examples where thats not the case 🙂
