I don't think the point is about an apocalyptic image of people cogging up and dying in the corridors or whatnot. It's the lack of equipments like ventilators. Also it's confirmed from many sources that the medical workers are all stretched to their limits and some of them even died from overexertion. That's probably much more convincing than some random videos.
Here a similar one from Begamo, Italy https://youtu.be/lcK2mzuO6MU
And now, where is the truth? I would like not to be infected. I try to avoid being infected by flu as well. But maybe we really are overreacting. We don't have immune system trained for this - that is problematic. Elderly people and people with health conditions should be isolated. But that's probably it. Once the population has enough people with trained immune system, it will be "like a flu" or won't it? Who to trust?
