Looks like you also missed that the chip shortage is affecting automobiles. Many articles exist that can explain better than I can about why this isn't a quickly resolved issue.
By design, proof of work requires even more resources as more resources are spent on it. One might say that it expands to consume all available supply.
Because of that, no matter how many cards Nvidia makes, crypto miners will want them all, as long as there is money to be made in crypto.
(the most prominent example is stolen electricity, but also for many miners it's a form of cash laundering. You always get less money out than you put in, but it's clean cash. In China's case they can't get money past capital controls, but you can mine at a loss and sell the bitcoins in a jurisdiction of your choice, that's worth something to them. Also, many miners are front-running exchange trades or extracting other forms of economic value.)
that essentially tells you that the price is about to go up or down, so you can make money on the movement.

Most of what you suggest doesn't benefit from having significant mining capacity yourself. (Though one thing does.)
I feel like if Nvidia could, they would have scaled up. Why wouldn't they want to meet demand?
Cryptocurrencies give NVIDIA the perfect bullshit excuse that people won't ponder too hard over, because the story of modern media is simplistic... every story must have a "good guy" and a "bad guy". It has to be dumbed down for all the idiotic plebs like us.
Cards are still selling for significantly more than MSRP, so if this was the plan they're doing a terrible job of it.
It really is multi-modal market. And demand for that node, is different from automotive woes...
