And also, we should hope that proper triage will mean that the non-coronavirus emergencies that matter will indeed be allocated a bed, etc.
I have little doubt that this will be awful, but the counterfactual scenarios are difficult to evaluate.
Edit: CCP comrades downvoting this, here's how "zero new cases" is being achieved in your country: https://www.reddit.com/r/PublicFreakout/comments/fosodi/covi...
That said, the no new cases sure does sound like bullshit.
As does 50-60 cases a day per 1.5 billion people when your test accuracy is pretty much a random number generator (as Spain has unfortunately found out when they received Chinese tests). I'd have a much easier time believing 5-7K new cases per day. For China that'd be the same as 1K per day for the US, which for us would be not an issue at all, if it kept steady.
We all assume that this is so (and I hope it is), but this is not completely clear. It might be that for covid-19, help from the medical system doesn't matter much, given our current state of medical knowledge and care. And iatrogenic harm cannot be discounted. Certainly we cannot ethically run the experiment.
As a single anecdatum, there was a (BBC?) piece on a hospital in the worst Italian region, showing a number of people on ventilators. The narrator explained that the staff was demoralized by the fact that everyone they had put on a ventilator died anyway.
