The Feds archive all encrypted communication, including supposedly untraceable Monero ring signatures, so that they can decrypt it sometime in the future when they have (and they will at some point) a strong enough quantum or a cryptanalytic exploit. It may be safe enough for pragmatic reasons to want secrecy like selling drugs, but if you want secrecy for philosophical reasons then you should know that even Monero won't really give you it.
