I'm not sure that's true. While abundant in the universe, there's a fairly finite amount of helium here on Earth, and once it escapes, it leaves into space for good. The US even has a strategic helium reserve. The shortage of helium was reported back in 2012 [1] We really need that helium for things like MRIs and chip lithography processes.
