These rules do not exist because the government used them as loopholes, these rules exist because citizens used them as loopholes to sue other citizens :) The government was already protected. For example, you literally cannot sue the US government for torts without its permission. This has been absolute since day 1 of our government. The government has decided to abrogate immunity in a bunch of situations, but in general, the government was already protected from whatever it wanted to be.
