1. True 2. Intel abandoned Optane, so availability will be spotty 3. Encryption is not always plausibly deniable. And when it isn't, rubber hose cryptanalysis can be applied even if the key is unrecoverable. Data on a RAM drive, if it was turned off and the attacker didn't immediately freeze it (harder when they don't even know you use a RAM drive, and the case may be hard to open) should be obvious it is gone for any attacker who knows how RAM works. The point is less to protect the data and more to protect the owner from coercion through violence.
