The role of the US government isn't do things it believes are beneficial for itself. It's to administer the law consistently with the constitution. When it behaves in arbitrary way and implicates the rights of its own people in order to pursue geopolitical ambitions on the global stage, it is metaphorically pooping on the floor.
The constitution explicitly gives the government the power to regulate commerce with foreign nations. Nothing about this is arbitrary, it is merely the government catching up with new technology and bringing regulation of that technology closer in line with regulation of existing technology. Foreign governments or companies controlled by foreign governments have been prohibited from holding radio licenses since 1934.
