Yup. The reality is that you can't defeat the NSA unless you are able to design and fab your own silicon without any third party involvement, are able to write and audit your own crypto code with zero bugs, and are able to physically protect yourself from being "encouraged" to reveal your passphrases.
It's not worth seriously trying to defeat an organisation as well funded/staffed/connected as NSA from obtaining your chat history and nude photos.
And if you're that important of a target, they're eventually just going to pick you up physically, black-bag style, from nearly anywhere on earth if they can. The NSA is the US military after all, there's really nowhere on earth that someone is entirely safe if they want you (maybe under direct protection by Beijing or Moscow).
