If anything, “higher level laws” tend to add more restrictions, not more freedom. For example, Newton’s laws of gravity were not replaced by General Relativity, but instead become a subset of them. Newton’s laws are not invalidated by GR, only modified and restricted.
Yes, but the mastery of the superset gives us greater capabilities. No archer would have believed a missile could fire faster than the sound it makes. No people, before fight believed flight was possible. Before biology, it was believed illness was from the gods or fate.
At the same those greater capabilities gave us greater risk. Until the advent of the bomb, nobody thought it possible to end the world.
