Terminal text has no security, not a surprise there. You need to brush up instead of making wise cracks because you really do not understand client side encryption at all. Someone would not only have to steal your device in order to get your device private key because that is not exposed to internetworking devices, because if it could, then everyone who does banking on their phones would have lost their entire bank account as soon as NFT was out onto phones. I am talking about something ever more secure than NFT, that would only be a partial equation even if they could get it, they still would not be able to figure out the total local encryption. These are not a simple as you make things out to be by any stretch of he imagination.
