Well done…except you forget that we are not all US citizens. You blithely recommend of US cloud services as being 'safe' without giving any reasoning except blind patriotism that they have not been compromised. The exception in you list is probably Signal because it has open, inspectable source. Even non-US citizens can trust that.
However, there is another approach. Privacy is only necessary when when harm can be done by everyone knowing. For example, gays can only be blackmailed when exposure has penalties. Increasing some freedoms reduces the necessity for absolute, unattainable privacy.
