The lightning network will allow Satoshi's vision of cash to come true. They did discuss lightning but did not implement it as it was too early to do so. Once it is cash and people use it on Amazon etc it will be crazy value always going up for over a century (I guess that is what you mean by being like Gold - no inflation - back to an opportunity to have your wealth in a gold standard that cannot be inflated away by government borrowing and money printing). Amazon will take it as they can make money on money from a purchase. It will coexist with the USD and Fiat though - like radio coexists with TV. But yeah like Gold I just think for a lot of people you need to explain what that means as I think many people don't understand how Gold was used up until recently as cash or why the Governments and Banks broke the link for their own ends and made holding wealth almost impossible in USD, GBP, EURO, Yen, Yuan etc. And with the property bubble at a fizzled out end well without BitCoin in the future you will need to work harder to cover government/bank theft via money printing of your wealth. Unless you are in BitCoin.
