If you're strictly comparing using btc vs debit cards for shopping on the Internet, I agree it's not a huge breakthrough or game changer.  I think it is a way more secure but we have a system where you're not responsible for unauthorized charges on your accounts...  Imagine if you were responsible for unauthorized charges on your credit cards, nobody in their right mind would ever use a debit or credit card because the storage of those #'s is not in your control.

Also your assumption that you have to give up privacy for shipping is not correct though https://www.privatebox.co.nz

So are you concluding it's a useless idea because it doesn't make shopping easier for you?
