"Gold was seized by Roosevelt with Executive Order 6102 to prevent people from using gold as a currency"
That is not accurate. People were hoarding gold at the time, which was harming the economy. Gold currency was taken out of circulation by the government and replaced by a currency less prone to hoarding. Hoarding stopped because people were given money that was not worth hoarding -- which is a good thing for the economy.
"today physical gold has been bought by millions of people as a hedge against the world financial crisis"
Which is not a currency, any more than a building, a field, or a gun is currency.
"On these occasions and more people would use gold as a currency if they weren't prevented by law"
Nobody in this century is prevented from using gold as a currency, just like nobody is prevented from using Bitcoin as a currency. The only difference is that gold is not legal tender. People tend to gravitate towards legal tender as a currency, probably because people live in a society governed by laws and need to legally repay their debts (taxes and others).
