Buying Stuff with Bitcoins and the Greater Fool Theory

You can buy stuff with bitcoins on the website BTC map.org, but there are very few places in the world where you can do so. Buying bitcoins is based on the greater fool theory, hoping someone will buy them from you at a higher price. Unless there is a world war, it's unlikely that something similar to the gold standard will emerge. The world is too complicated for that. So, am I completely wrong about bitcoin's price? Probably. Should you take a chance on bitcoin? Well, that's up to you!
