You assume there is room to discount by 30%. That is, unfortunately, not a good assumption. On some cards it might be possible, on others maybe not. As for "milking", well that is supply and demand. The fact is, if the prices had been lower, supply would have been impacted even more.
My issue with an article like this is that you assume that all GPUs will deliver "value". In my opinion, if a GPU cannot deliver 60FPS at a minimum, then it doesn't have much value, regardless of the price. The RX 6500 XT seems to be the red-headed step child here. The 3050 also looks pretty lackluster outside of 1080p. If that's all you can afford, I would suggest saving up some more money or looking at used cards for a better deal.
