Governments seem to exist in many cases, to keep the current group who are in power today, in power tomorrow. Governments don't want to see anarchy on the streets, in a total apocalyptic scenario with total lawlessness. Whoever has the most ammunition, firepower and biggest gang controls each block in every city and town. Largest majority of people don't want this type of lawlessness.
When governments offer to step in and "solve" the crisis with SDRs, the population will be overwhelmingly in favor of the scenario that "saves the day". Look what happened in 2008. Many of the actions of the US government, under Geitner and Bernanke were illegal, but they were still hailed as heroes.
