The paper does address exactly that point. The longbow required sustained central support over many years which prevented rebellious nobles from quickly adopting it:<p>&quot;These features of longbow technology had two important implications for those interested in adopting it. First, centralized efforts were necessary to create a culture of archery. As shown above, these efforts in England consisted of laws supporting bow ownership and practice, restrictions on competing leisure activ- ities, subsidies for bows, and festivals and tournaments focused on archery skills. Because of this, the longbow could be adopted only by, or with the permission and support of, a nation’s ruler, who alone wielded the authority and resources required to undertake such e orts. Indeed, given the nature of longbow technology, to have even attempted to adopt the longbow without his ruler’s permission, a noble, for example, would have needed to successfully hide the fact that he was continuously training large numbers of archers for years—a highly improbable proposition.
Second, conditional on a nation’s ruler adopting longbow technology, a usurper noble with an eye on the Crown, or a prince interested in independence for his territory, could lead an effective rebellion against his ruler by supplying the inexpensive weapon to large numbers of citizens, whose ruler-sponsored training and practice with the bow had made them proficient archers. Thus, to be willing to develop longbow use in his country, a ruler had to be confident that his efforts would not be turned against him.&quot;
