False, a government could have stopped international travel and fix the problem at it's root, but capitalists wanted to travel aroudn the world and now you pay more. Same shit with anarchist that protested like retards (at least in my country) that they don't want to use masks and today they are waiting 3 hours for a vaccine because the giant number of deaths in their family finally opened their minds.
So you are fucking wrong, greed and anarchy caused lot of death and financial lose, but I am 100% sure your scenario where everyone traveled without masks around the world and in public places is much better feel free to ignore reality too.
