> You don't actually "lose" capacity, you just move to higher-valued special niches within the overall industry
That's not what people mean by "lose" capacity.
Suppose DRAM companies expand capacity because prices are high, then demand levels off, the price crashes, and they all go out of business except for the one in China which gets a government bailout. That's fine, right? We're not interested in making DRAM, that's a fungible commodity, we want to make iPhones or something. (They make those too anymore, but never mind that.)
What happens now if China restricts what you can buy to give an advantage to their own companies who are trying to displace you in the higher-valued special niches? Or just raises the price for you and not them? What if there's a trade war? Or a conventional war?
When you still have a domestic industry, you go to them and have a source for the commodity. If only one country becomes the sole global supplier and that country isn't even particularly friendly, that's bad.
The way I see it, China has leverage once you arreive to that dependency situation. That leverages goes away the moment they restrict exports and every country scrambles to create local production once again.
We are seeing that with some rare earths, even tho china is back into exporting them (except to japan, I think?) everyone is looking for alternatives already. They may have killed their industry 10 years down the line for playing with the export lever a bit too much.
Just like how markets punish the ram cartel creating a chance for cxmt and ymtc to enter. It would create a chance for western companies to do the same if china messes with the markets they have "cornered".
The domestic industry is still there, only instead of mass-market DRAM it has started making higher-valued varieties of the same stuff. If there's a trade war, they can easily reconvert to making the mass-market stuff, just at much higher cost. You can't expect more than that, since they never really were as big or as low-cost as the lowest cost suppliers can be in normal times. That's not "losing" capacity, it's just acknowledging that you can't create capacity out of thin air.
No, the domestic industry stagnates (at best) or disappears (at worst).
You can't just spin up a 2nm wafer fab when the latest you've been running is a 300nm process.
Compare: US shipbuilding industry to China or SK.
We don't want to spin up wafer fabs because, historically, they had a tendency to turn into Superfund sites. That's why the more modern approach is to build the fab in the middle of a frickin' desert.

Factories, tooling, supply chains, and engineering knowledge aren't fungible in the way they would need to be for your statement to be true.
Different types of DRAM can literally be made from the same already-etched wafer. The DRAM bits themselves don't change at all. What's different between DDR4, DDR5, and HBM is the IO interface to the chip. Changing this does not require significant retooling or relearning.

"easily" is doing a lot of work in that sentence. Depending on the good and what they switch to making, this may neither be easy nor quick.
If the domestic industry had the capability of competing with China on mass-market goods at a profit but just chooses not to in order to pursue a higher-profitability niche, why not simply grow and do both at the same time, instead of yielding the mass market to China?
In my mind, if it can't do that, then it can't make the volume that China does at the cost that China does, which means it really isn't as capable as Chinese industry.
Perhaps at one time it could have, but those muscles have atrophied.
Because by pursuing a more profitable niche, you can grow quicker and make more profit. If you really want to do both, you enter the mass market from above, with only slightly higher quality products than what the market leader offers. And you do that after your position in the more profitable niches has long been secured. It's silly to do it any other way.
> which means it really isn't as capable as Chinese industry.
But this was always true. There was never really a time when Western industry was producing as much and as cheaply as China is today - that's the whole point. It makes more sense to diversify away from that, because non-trivial real-world markets will always reward increased variety.
Higher valued varieties, or just higher priced varieties, that no one wants to buy?
