“Mathematical and physical laws set the boundaries for human laws, not the other way around.
In the days of analog phone lines, it was possible to capture a conversation without the participants having a good means of stopping you. So we got wiretap laws regulating this.
Now it is digital and there happen to be techniques — which could in principle be carried out with pen and paper — allowing secrets to remain hidden from third parties watching the communications.
The government seems to have gotten the strange and power-trippy idea that just because they used to be able to wiretap with the previous technology, they should always and forevermore have that ability, math and physics be damned.
They are essentially arguing that you should not get to carry out a particular set of calculations on a piece of paper without sharing the results with them.”
