Does such a thing exist?

I've had a concept in my head. I wanted to know if there was anything like this out there, or not.

OK. Everyone remembers e-gold. All your money was backed by gold, and would fluctuate when the value of gold went up and down.

Is there any system, like an official bank account, that does this? Basically, it would auto invests/purchases either gold or gold ETFs with the money, and I can just withdraw it, and use my money normally, hopefully attaching a debit or credit card to it?

Is there anything that exists like this, or anything remotely similar?

Thanks, in advance.

kinda there are one or two out there the one i know of and know people that have used 1 of them is bullionvault.com, cant remember the other ones though, i also saw something on flippa where you can join some kind of silver coin club where they send you one silver coin every month but it seemed like he was really selling an affiliate site. are you setting up a business in this area, if you care to share the idea i might be able to help, i a have been a commodities broker for 11 yrs and want to quit and do something less stressful from home which is why i joined this site.
