Yes. If something serious happens. Suppose Al-Qaeda flies 10 airplanes into 10 buildings in Brussels. I would be good to have a government.
Otherwise, we should not underestimate the work of governments. Every citizen will feel negative effects mid-term if governments don’t perform well. In Western democracies we seem to take everything for granted, and would only notice when things don’t work. Let’s take Egypt as an example. The purpose of the fallen regime was to get rich. So some dozens of corrupt people became billionaires or millionaires. But the country isn’t prepared for the future. Academics have to sell fruit. Computer outsourcing is done in Bangalore not in Alexandria. Cutting edge research happens in Israel but not in Egypt, even though the latter country has 10 times more people.
Ergo: The Egyptians will notice once they get a real government interested in the prosperity of every citizen.
So we should not belittle the role of governments.
