Even now, with a significant degree of globalization, the bulk of economic activity by ordinary people is local or national in character. Most people rarely make payments abroad or receive money from overseas. People mainly earn in local enterprises and buy goods in local retail. By and large, the idea of global money is abstract for them.
Any sane government will not blindly accept global means of payment within its country, and patriotically-minded elites will be unambiguously hostile to it. Bitcoin cannot be an exception; it too is perceived as a threat. In all countries, authorities are particularly wary of cross-border private payments, as they can finance anti-government activities, terrorism, and crime.
But it is not the criminal world that concerns the authorities most in this regard, but rather the fact that global Bitcoin is convenient for ultra-globalists seeking an extreme form of cultural and economic unification that does not envisage a significant role for national states in the future. In the confrontation between sovereign states and the growing influence of transnational corporations, the former suffer enormous losses. Their officials are bribed. Their citizens are imposed with alien worldviews. They are monitored online. Retailers, social networks, and other IT giants openly plan to introduce their own monetary surrogates, which will deprive all countries of some tax revenue.
The presence of borders is a benefit. Competition between countries is vital.
This is a proven, natural mechanism that has worked well throughout all epochs. A state that eliminates competition within itself can drive its citizens into poverty. However, on the international stage, it still represents value by stimulating other countries. The Soviet Union is a prime example. The introduction of an eight-hour workday, recognition of women's rights, the development of atomic energy, the conquest of space, and much more in the West are largely due to the Soviet Union's efforts. And after the collapse of the socialist camp, the union of democratic states began to degenerate rapidly.
The erasure of political and economic borders also undermines moral boundaries. The meaning of cultural diversity includes the ability to compare oneself with other people, and therefore, the ability to look at oneself objectively. The dominance of global cultural clichés may have seemed harmless a few decades ago, but today, it has already manifested itself in completely grotesque forms.
