Your explanation of counters and uses is backwards. The uses keyword causes the card to be discarded when out of counters. If the card doesn't have uses, it stays in play.
Actually@@NelsonAllOverCards was not incorrect. I was the one who asked and then I went on to confirm the Rules Reference page 10 of the core set and page 18 of v14.2, it says under KEYWORDS that once "Uses" are spent the card is indeed discarded.
