Yes, air-gapped and the entire operating system is running off overlayfs + tmpfs, so no data persists after power off. There's also a problem with TEMPEST emanations from the computer's display - the problem is almost non-existent on mobile devices such as smartphones, which are very well shielded. So disable the modem physically, and run everything locally. Of course the risk of targeted surveillance still exists, and nothing is going to stop a hidden camera from being placed in your home. But in most cases there would be no reason to ever place the average person under such surveillance. So the bulk mass surveillance of the population would be hindered. And they won't be able to persecute people for reading or viewing certain things anymore. So that puts an end to the morality policing that has been enabled by the Internet.
