Is identity theft not their issue? That site includes a history of your buying/selling habits, your address, your phone number, your payment information... screw the money itself, there's a lot more damage a nefarious eavesdropper can do than make a purchase with your account in Belgium.
Identity theft is non-thing, a lie made up by unscrupulous creditors to pretend it's not their fault for incorrectly authorizing a criminal then charging you for it.
Think about it: This information you're revealing to eBay is basically the same for any other online merchant. If that's enough to "steal your identity", where does the problem really lie?
