I agree, but I'd also like to add a more specific cause to this idea. Like you say, technical measures aren't a bad idea either, but only drag things on.

My political view is this: both the right to communicate and the privacy of communications need to be treated as a fundamental human rights, just as freedom of speech is currently treated.

Then there are subjective measures. Breaching these rights may be warranted in certain specific situations (just as free speech is), but the current processes don't seem to go far enough to protect us. Even freedom of speech seems to have been curtailed too far in recent years. We need to have the political will to push back on this. But this can only happen if, first, we add freedom of communications and privacy of communications to our list of fundamental human rights.
