They should at the very least be building several emergency hospitals right now to create beds, but they are not. What do you think that would usefully achieve? The problem isn't just beds. They don't want most people with the virus to go to healthcare facilities, they want them to stay home and avoid spreading it around. The problem is intensive care and isolation facilities for the most sick patients who really need extra help. These require equipment, medication, clinical staff, etc. They are trying to increase the number of these facilities available, but the capacity will go from a few thousand normally to a few thousand more in the entire country.
