More than that. Here in little old Adelaide, I personally know at least three people (probably five) that easily meet your threshold and I reckon there would be no less than ten... in a population of about 1.2 million. Say the western world has 2bn population, that implies there are probably 15,000-20,000 people with a modest stockpile. And there are probably as many again in China and India (don't forget there's no shortage of affluent people there despite the hordes of peasants).
"2 per US state" is a hilarious estimate when there would be a few hundred in each of CA and NY alone. Think how much business Freestyle and B&H do.
