Some people trot the argument that it's OK for the government to compel apple to deliver the backdoored firmware because the measures it would circumvent are not of cryptographic/information-theoretical nature.
Then one could expand that argument by saying that compelling physical reverse-engineering is also OK because the devices are not built to be physically impossible (read: laws of nature) to pry open.
