I don't see "store of value" mentioned anywhere in the white paper. I do see "peer to peer electronic cash".

Any privacy features built on layers on top of Bitcoin so far sacrifice self-custody, permissionlessness, p2p, or final settlement.

Just look at eCash eNuts that just dropped. Not only can they issue unbacked tokens - they literally and metaphorically hold your nuts. I prefer having the option of uncucked privacy, thanks.
