Magnets are very weird. Up until now, we don’t really know what causes magnetism or how it works. We just know some rocks have it and others don’t. Also, magents aren’t super massively available in nature.
I’d hazzard a guess that guy refers to magnets the same way we SHOULD treat helium. It’s a precious rare non renewable resource and we squander it like it’s nothing.
