Electromagnetic shielding around your computer can defeat this.

If the NSA has determined your location, you are already probably toast.

They key about IP obfuscation anonymity mixing is the NSA not knowing who is doing what.

I plan to be retired by the time the NSA starts trailing me. My essential work will be done over the next several months, then turned over to other devs to carry on. I need to make sure ALL of those other devs can not be identified.

As for future-proofing, then wider keys such as 512-bit ECC and super singular isogenies against quantum computing can be considered.

No we don't have to give up. There won't be any place on earth to emmigrate to. This totalitarianism is global this time. You have 3 axis powers pretending to be antagonists who are really working together to enslave the people, and between them their militaries can reach any corner of the globe. China has a huge standing army to deploy to South America, Africa, etc.. They will hunt you down.
