Nothing can stop anyone anywhere from cloning a storage device. You can encrypt it however many times you want, but it can still be read at the block level.
I’m not sure where the paranoia lands or is focused towards, but there is no storage device that exists that can’t be copied, so if that’s your hangup, you should just accept that and move on. If someone has physical access to your drives, then can copy it, but whether they can decrypt it is up for debate.
As the saying goes: given enough time and effort, anything can be brute-forced.
