Same here, so I don't understand the premise of the post.I have never heard any reloader claim they could reload for infinity.
I had a friend who got me interested in handloading because he did it, and I saw that it wasn't difficult. I actually started picking up my brass and buying the occasional 1k of LPP before I had a press.
Since then I have weathered 3-4 "shortages" without difficulty. I can't reload "for infinity" because I won't live for infinity.
But I have enough components to last the rest of my life, and that's good enough.
