1. You still have to pay capital gains taxes. A short-term capital gain regardless of how long you hold it.
2. All the currencies he mentions have inflated too.
Canadian dollars >1000% since 1971
Australian dollars >1000% since 1971
Euros >100% since 1998
Mexican Pesos - no data but sure it is up
Swiss Francs >300% since 1971
British Pounds > 600% since 1971
Swedish Krona - no data but like all governments it is up
But you get the point, government uses currency inflation as a means to tax since it is hidden and there is generally about a 4 year lag before the price inflation hits.
The best stimulus you can give your country is a deflation rebate, balanced budgets and surpluses.
