Think about Monero - it's a lot more suspicious to be dealing with that than regular bitcoin.
For privacy advocates it's fine, you aren't doing anything wrong by using e2e and monero, any govt looking at you won't be able to get past reasonable suspicion.
But if you're a criminal you're basically glowing in the dark by doing this stuff. Regular phones are also encrypted! Facetime is e2e? What was the point of the "AN0M" phones. What did they give you except a supply chain risk and a 100x SIGINT interest factor than a normal person.
