Increase production of hand sanitizer, masks, gloves, test kits and other supplies as much as possible. Ensure all medical, food and other essential workers have access now and for the foreseeable future to the supplies they need to perform their jobs safely.
Provide masks and hand sanitizer to every citizen and at a minimum recommend usage at all times outside of the home.
Establish working contract tracing programs, so that spread can be limited.
Once those things have happened (they haven't), re-opening could start to be done safely. Until then, the government's role should be to provide financial, medical and food assistance to the fullest extent possible so that the people and companies who are twiddling their thumbs don't die or go bankrupt while they wait.
The government can literally print money. They could begin distribution tomorrow. They cannot print masks, tests, hand sanitizer, vaccines, gloves, food, etc.
