If you are a person of interest, it is only a matter of time to break encryption. It may make it difficult to break it but possible. There is no 100% privacy and security. Did you watch the video I mentioned?

They never said what they were trying to break. If it's disk encryption and you're forced to give up the key, the courts already decided you can be compelled to provide it. If it's end-to-end, the feds have been fighting to break that for years. If they can clone the drive without you knowing, that's game over for any non-quantum encryption. But they can't force you to remember a password you don't have. So it's less about "can they break it" and more about what they already have access to without your cooperation. But honestly, most of us aren't that interesting. They go for the low-hanging fruit first. For the rest, it's just a matter of time and budget. Which is why I prefer the Lightning Network for my own transactions. It's not just private; it's cheap, fast, and the fees are fractions of a cent.
