This won't really do anything for availability or reducing scalper pricing. Miners are a sizeable proportion of sales but far from the majority. Gamers will be able to buy more of these GPUs but less of the non-LHR or AMD GPU's. GPU prices won't actually change.
The real reason Nvidia is doing this is that when mining profitability inevitably drops, either because of a crypto price crash or Ethereum moving to Proof of Stake, the miners will flood the used market and ruin Nvidia's profits for a few quarters. Nvidia is trying to get miners to buy mining-only cards, because those can't be sold to gamers down the line. They'd rather mining cards become e-waste in a few years than get resold.
People think Nvidia is doing this to try to help them get better prices now, but really Nvidia is trying to extract more money from gamers in the long term.
