If you secure any of that data with encryption, then you don't need bitcoin. Emails? Encrypt them and a Google hack is still fruitless. Change address, require a key sigature, moving the Bitcoin requires the same but costs mining fees, a signature costs nothing but a few CPU cycles. You're adding unneeded costs. Cryptography already defends against the phsical realm. No amount of kinetic energy can break a signature, or encryption. Why spend sats if this is true? Requiring bitcoin as payment to decrypt or receive a digital signature is fine, but that's just one size of the trade. The other is just cryptography. No value transfer needed.
