at some point there is need for crossover between the systems

At what point would that be?

Your bank has no legitimate reason to cross reference your account and your phone calls
nor will they as they is no business reason for them to do so.

Sure there is. And they have a business reason to cross reference my
account with my health information too. Both are valuable, and banks
are a business. I just don't want them to.

My employer has a business reason to cross reference my bank account, my
health information, my mortgage information, my phone calls, and
everything I do on and off the job. I don't want them to.

And anybody who gets any of my information has an easy method to get all
the rest of it. I don't want them to.
