What is the speaker's suggestion for users to send money without creating an account?

The speaker suggests using a transfer system, possibly implying the use of an intermediary or a different method that doesn't involve creating a new account.

What is the term used by the speaker to describe a method that allows sending money without changing the account code?

The speaker refers to this method as 'Final IZer', a technique that seems to bypass the need to modify the account code for transactions.

How does the speaker propose to prevent the 'Final IZer' technique from being used?
