It's clear that market capitalism isn't resilient or robust. Our engine must always run on red and sooner or later it's going to brake down.
For instance the fact that different countries are trying different tactics let's us compare between them to see what works best. Without nations we'd presumably have the same response everywhere, so we couldn't look to e.g. South Korea to learn anything. Singapore's previous experience in combating SARS wouldn't have gone anywhere because it wouldn't have reflected global priorities.
As for your last paragraph, that's just bog standard Marxist catastrophism isn't it? He was claiming capitalism's inherent contradictions would cause global collapse in the mid 1800's but he was wrong. It's been a standard refrain for centuries but where did this outbreak start? A communist country, that oppressed the doctor who tried to raise the alarm. Not great evidence for your case.
Marxist catastrophism? Never heard of it, but it very clear that the dogma of modern neoliberalism calls all other ideologies or opposing thoughts marxist. Is it not possible to critique our current system without being called a marxist? Marx wanted the means of production in the hands of the workers. I couldn't care less, I just want to be able to live in a society that has the ability to address problems that or not profitable in the short run. What should I call myself?
Marxist catastrophism is a very specific thing. It's not a fancy placeholder for "anything that's not neoliberalism" (a term which is arguably itself poorly defined).
Marx is famously known for a few slogans, but he spent his entire life writing. Marxist catastrophism refers to his written vision of the future in which, roughly speaking, capitalism would collapse into catastrophic anarchism due to its internal contradictions (as he saw it) and eventually be replaced with socialism. Interestingly this vision of his came to him as a young man, before most of his other ideas were well formed, and stayed with him his entire life. There's a good description of it in this biography of his life (starting page 52):

Johnson argues that his vision was primarily a poetic vision, that is, he saw the poetic vision of a society in flames and then worked backwards from that to derive his political ideas, which is one reason why they don't hold water and why he had to rely on various kinds of intellectual fraud to support them (like manufacturing quotes, using very obsolete sources, etc).
When you argue that "market capitalism isn't resilient or robust. Our engine must always run on red and sooner or later it's going to brake down." you are, whether you know it or not, walking a well trodden intellectual path. It's all been heard before but kind of like peak oil, didn't actually happen. Capitalism proved very robust, at least compared to the proposed alternatives. There have been quite a few collapse of communist regimes, but no collapse of any capitalist country. Even blowups like the GFC were over within two years and back to business as usual.
Business as usual.
Apart from that I agree. We forgot the ‘enlightened’ self interest part of capitalism. My wealth means nothing if the planet has to die for me to get it.
I'm all for creating brakes and maintenance periods.
Less globalism, less ability to freely travel == less risk to spread the virus from country to country. If anything, nationalism does the contrary of what you claim it does. In fact, by closing their border right now, countries are insuring that no foreign traveler is going to bring now CORONA cases to their country.
If nobody could travel to and from China, the global pandemic would not have happened.
