Not sure if you are just clueless or trolling.

Paper is recommended because it is cheap and reasonably reliable if kept dry. Modern computers are also inherently insecure. That is why the advice is to store your private keys for savings on something that can be readily observed and secured (in more than one physical location).

Storing Bitcoin on paper is superior to storing money under your mattress because you can redundantly split the keys into several locations.

The difficulty is that ideally, you want some way to seal these pieces in a tamper-evident way. I have tried signing the seal on my envelopes, but am not sure how secure that really is. I saw an hour long talk about a year ago on Youtube about various types of seals. Essentially, if security is extremely important, you want to compare high resolution before and after photographs of a seal that exhibits tool-marks. Most truck seals are apparently modified zip-ties.

Technically, I think Bitcoins are stored in the block-chain: and are public information. What you have to secure are the private keys for moving those Bitcoins.

and how would an ID system work? the best option we have now for easy security is an ETF. otherwise, if you don't know how to manage your coins, you shouldn't be having them in the first place. it would be nice if everybody knew how to protect their coins, but that's just not the case.

But splitting up the codes on several papers is even more burdensome. Like having to store cash under several mattresses.

Don't get me wrong. I understand that some people want to manage the security of their bitcoins themselves. Just like how some people want to own and store gold physically themselves. The problem is when Bitcoin should be used as a more general currency. Then it needs to become much more convenient to keep safe.

But what happens if your service goes away? Will I lose my coins?
    GreenAddress signs each transaction with its own key in addition to client-side signing by user's keys, and funds are stored in 2-of-2 multisignature outputs requiring both signatures to spend. The drawback of it is that you cannot control your funds without GreenAddress' signature, so you are right to worry that you can lose your coins.

    But! We have solved this issue by providing nLockTime transactions which essentially make deposits 'expire' after some time, which allows redeeming them without our intervention after this pre-set period of time. It is enabled by default when you have email notifications and two factor enabled.

    This allows you to keep your ease of mind even in case GreenAddress disappears with its keys.

    It also means that every time the funds expire the user has to re-transfer them. This can be automated on login and notified in advance via email or manually done.

    For redeeming the funds after expiration, you can use a tool we've developed specifically for this purpose - see Gentle and its project on GitHub. It's open source!

M of N transactions allow you and a payment processor to share the security burden. Both you and the provider get a "hot" key for day-to-day spending, while you keep a third key in cold storage in case something ever happens to either of the "hot" keys.

Currently BitGo and Green Address listed here appear to implement 2 of 2 transactions (meaning no cold storage back-up). According to the Green Address FAQ funds can be recovered if they go out of business because they use a nlocktime transaction to let you retrieve the funds.

You mean like this?

Sounds too complicated for the average Joe and your ordinary soccer mom. People in general just want to click 'Pay' and be done, without having to be concerned about security details.

Ha ha. No, seriously. I'm looking at it from a conspiracy power elite perspective. Bitcoin is just a pilot project. And eurocoin is just a stepping stone to a global digital currency. See through the power elite, I can. :Yoda voice:
