Note: All the blinding in Lucrative is done client-side, the mint is agnostic
if blinding is done.

Allow me to rephrase your question into "Why anonymous digital bearer
instruments? (Instead of non-anonymous ones)"
Also, the quotes below use 'digital cash', but the same applies for all DBI.

"Anonymous digital cash can be defined as digital cash--for the purpose of
allowing personal financial privacy-- that is untraceable and transactions made
are unlinkable. 
Briefly, "untraceable" means a digital cash withdrawal cannot be associated
with its subsequent deposit, while "unlinkable" means that it is impossible to
associate two different digital cash transactions made by the same person with
each other." [JOG]

"If the bank knows what is going on in your account, then potentially so can
anyone else: the records can be seized, or surreptitiously accessed by
computer, or a bank employee can be bribed to make them available. (In this
respect, it is useful to note that the system of Swiss numbered accounts was
created to protect bank customers from bank employees. Bank employees,
observing what occurred in a customer's account, could possibly subject the
customer to blackmail.) Anonymity requires first and foremost protection from
the prying eyes of the bank." [JOG]

Anonymous DBI relies on technology to be anonymous. Not on the believe that
the mint will respect your privacy just because they like you.

I could go on quoting that whole article, but better read it yourself :)
