So to break your application's security model, all somebody has to do is
use their PC and they have full access to their account?
Or get hold of the copy and paste buffer?
Or the application's config files?

Or your users might be sensible enough to not trust a role-your-own
security model, and prefer to memorize the password than to trust that
nobody will get access to their PC.

And why would they bother doing that when they can sniff the wire and get
the passwords in plain text? You should assume your attackers are
*smarter* than you, not trust them to be foolish.
