CDQ, it's about the abuses of the British, who treated people's homes as fair game for lodging soldiers. This caused hardships that the founders objected to. It's relevant today because tyrants and despots use people's homes int he same way. Cuba is one current example, as are many of the African countries. Germany. Russia. Japan. Mexico. Bolivia. Argentina. They all did it. The expectation was not just lodging, but food.
The founders used history as a reference, and knew it was not just the contemporary British who were to be feared, but that there was much historical precedent.
The 2nd amendment is based on the same mindset, explicitly forbidding behavior by the government that history had shown to be real dangers.
