How serious should we really take such initiatives? Since the 1990s, the topic has popped up regularly, but apparently by people with little technical expertise or economic imagination. Regardless of how less these people value free speech, any state with a market economy, i.e. in which economic activities are based on the initiatives of its citizens, must protect the secrecy of communications between its citizens simply for economic reasons. Otherwise, the country's economy would be fundamentally exposed to foreign powers, putting national security at the highest risk: financial transactions could be more easily manipulated, trade secretes more easily stolen, etc.
