I think that people is skeptical because money is one of the only things that you can use to buy everything. Yes, gold can be used as a way to keep your money secured, but you can trade gold, and very rarely buy something with it.
Unfortunately, people believes in what they see, and what they know best, and you can't convince a monkey that honey is sweeter than a banana, or can you?
But you're right, with time results will come. Houses will start dropping, cash will get devaluated year by year, and everyone will be aware of everything but probably way too late, and at a really big loss.
