In a previous thread, a comment was posted about uranium supply not being less than demand. As such the logic goes, this means uranium miners and stock prices will stay stagnant as there is nothing forcing up the price of uranium fuel.
But if the supply of uranium was limited and less than demand, then countries would not build new nuclear reactors as obviously uranium would not be a good fuel source if there are problems getting enough of it.
The same sort of argument goes for gold as a circulating, physical money. They say gold is not a good sort of money now as there is so little to go around for the huge world population.
