This guy doesnt understand economics. The more uses for something the cheaper and more available it gets. Aluminum was one of the most expensive and rare elements on the planet until the government decided it wanted lightning rods on public buildings to be made from aluminum. (This was, at the time, like ordering lightning rods made from gold.) This created a market and chemists immediately invented processes to produce material to fill that market. Unlike gold, aluminum is the most common metal in the Earths crust. Market/use = cheap/abundance.
This mans thinking is typically liberal. If you use something you use it up; therefore it must be regulated by the government. In reality, the more you use something the more there is of it. Take oil. In 1960 alarmists said wed be completely out of oil by 1970. In 1970 there were more reserves known than in 1960. So, they moved the date to 1980, then 1990, then 2000. Each decade saw more known reserves. Now, we know that oil is produced by biological processes near the earths core, not fossil bones (see link below.) Even if that werent the case, a market for oil would mean somebody would invent a process to come up with oil. (The Nazis did; coal to oil.)

Only if there is an available source for it. While greater demand creates a price support for the economic supply of a material, it has to be available for that to happen.
There are very few sources of Helium in the world.
“This guy doesnt understand economics.”
It has nothing to do with economics. Helium is scarce ( on earth) and you can’t make it in the quantities that it is being wasted.
