Very interesting. But reading, it seems that the key feature is the required time to power down or cash out SBDs. Steemit has created a system that, by many points of view, is more safe than other cryptos... But it has some problems. It is safer also because your funds can't be speedy stolen.. Because your funds can't be speedy used. You have a reasonable time to intervene and restore situation.

Now let's step back, one moment.

What is one of the key equilibriums in every form of money and crypto? It is the equilibrium between usability/freedom and safety.
Blockchain tried to change this equilibrium allowing the decentralized safety of blockchain - that allows a greater using speed and freedom and provides great safety.
Steemit simply moves in this equilibrium. This safety has a clear trade-off: as I said above, your funds can't be speedy stolen.. Because your funds can't be speedy used. You have a reasonable time to intervene and restore situation. By this point of view, steemit has created a sort of safe-deposit box: you can cash out.. But slowly.

So, we can simply say that steemit as free money is safer than other crypto, maybe. But it isn't a safe money, because money for definition is liquid. It can be used everywere. And steemit? 3 months to power down is not the definition of "liquid and available money". "3 days for cash out" is not immediate availability.. It is a safety measure that you have to ignore for everyday use. You have to hold an amount of steemit/SBDs immediatley available, maybe on exchanges or on every other services that guarantees immediate payments.

So, thank you for this very interesting post, but i have many doubts that this "slowly-available" form of steem can be considered as a more efficient form of money. No doubt that, as crypto, it is a safer way to protect your funds. But as money, in my opinion 3 days or 3 months to cash out are a problem.
