Not at all -- many banks provide anonomous accounts. The only
requirement is a secure authentication mechanism that shows
whoever is withdrawing funds is the person who opened the
account in the first place. The usual is a number signed in
longhand, related to, but not the same as the 'account
number'.

No bank will give you money just because you belong to a depositor
organisation. You have to be designated and they must have your
signature on file. If they have your signature, they won't give a
tinker's dam for your "true identity". This is functionally
indistinguishable from having the private key to match the public
key provided by whoever opened the account.
You may not have noticed the last time you opened an account, but
I'll bet no one asked you for any proof of identity.
