By the time that happens, Bussard collectors will probably escape from the realm of fiction.

Yes, but right now it’s “cheap” because it’s a byproduct of natural gas mining. As we transition off fossil fuels it won’t be so easy to acquire.
One of the reasons the shortage was alleviated was the expansion of gas mining and the subsequent discovery of a bunch in Tanzenia.
