The problem is that it is not sure you will get your gold back. Which is why repatriation of gold happens often (Texas), why the France did it in 1963.
So that in 1971, US could not steal the gold of France when it stopped convertibility of gold to dollar.
Moving gold, is the only way to know you will get it. Paper gold is only a promise that will break at the first crisis.
That said, granted, paper gold is nice for gambling, but storing your wealth in it is reckless. (cash is better than paper gold on this aspect)
But in a nutshell, Bitcoin can't reach 1000 tx overnight. It might happen in the future but it will be a slow process.
Meanwhile, the business cases involving low value transaction will get kicked out of the blockchain.
Then maybe, we'll get the same thing than now with gold : Real Bitcoin for storing wealth, but paper Bitcoin for transacting it everyday. (coinbase Bitcoin)
The only thing that make me think the story will not repeat is that I think better, trustless way of transferring Real Bitcoin off chain will appear. (Micro Payment channel is an example)
And there are other way some devs are working on right now.
However, I don't think those methods will be used at all only until we hit the problem for good, and will be used, only IF usability is better than "Paper Bitcoin" services like coinbase.
