You were describing an idea for minimizing the role of speculation on the value of cryptocurrency, and your proposal was to peg the value of cryptocurrency to something which is valued largely on speculation. If you wanted to say that tying the value of cryptocurrency to gold would stabilize it, then you should have said that instead of saying the stupid thing you actually said.

If you're comparing cryptocurrencies and currencies issued by nations you're comparing apples to oranges. You can't make realistic assertions about bitcoins based on currency--they're just too different.

But most nations use electronic currency with digital ledgers and new currency is generated whenever a certain cryptographic function is made - namely, a messaged signed with the key of the central bank.

Can you show me any graph of the value of a nationally-issued currency that behaves like Bitcoin's? The most stable currencies show <10% volatility, while Bitcoin shows volatility of >100% over a given year. The most volatile currencies are almost entirely inflationary, while Bitcoin can be deflationary a great deal of the time (even counting the drop from $1000+/coin, I'd be still up more than 1000% from when I originally bought Bitcoins). Not a single government-issued currency in the world behaves like Bitcoin.

If you want to talk about the technical implementation details, fine, there are some vague similarities, but those are not by any means the defining characteristics of a currency. Currencies predate computers, so computer implementation arguments about what a currency is are pretty obviously bunk.
