With all due respect, you're conflating the issue. Many people here are, not just one person.
If someone swipes your credit card number and runs up the balance, you'll be our of available funds as well. It's a &$*%y situation no matter how your shake it.
If the bank issued card that is attached to your checking account has a Visa or Mastercard logo on it, it is protected in the exact same way that a card that we commonly call a credit card is.
For instance:
I have $5000 in my checking account. Someone swipes my number, processes as credit (can't process as debit since they don't have my pin), burns up my $5000. I call the bank, file a claim, I'm getting my $5000 back right then and there.
I have a $5000 limit credit card. I don't carry my bank issued card because it's "too dangerous." Someone swipes my number and spends $5000, I'm not spending another penny until I call the credit card company, file a claim, they flag the charges and restore my available credit.
It's literally the exact same scenario, just a different place you have to call. In either case, you then have to forfeit the card number, get a new number in 7-10 days (some banks can do cards on the spot), change all auto-charges attached to that number. It's a royal PITA that the innocent party has to go through.
