It's never too late. Most countries re-instituted mask wearing and store closures.
Alternatively, you can do as Trump tells you.
Check my avatar. I do what makes sense to me. I don't listen to Trump. In any case, it's the governors of the states that set the rules, when and when to wear masks and when stores can open. Blaming or crediting Trump is just about the election. He has little to do with it.
Here're the current rules regarding which businesses can reopen for my state of New Jersey and what safety protocols they have to follow. It is issued by Gov. Murphy, a Democrat. I copied a few. You can see the rest on the linked page. I didn't copy the protocols for each type establishment as they were too voluminous.
BUSINESSES THAT REMAIN CLOSED
Shared space tutoring service facilities remain closed to students and clients. Tutoring services may offer remote learning.
Adult Day Care Centers remain closed.
Note: Any establishment open to the public, including bars and restaurants, must cordon off any indoor or outdoor dance floors to the public.
BUSINESSES THAT MAY OPEN
Workplaces that do not have walk-in customers or products for sale, including office spaces, were never closed, but must allow employees to work remotely if their job can be performed remotely. At a minimum, businesses must have policies that require individuals to wear face coverings indoors when in close contact with others for long periods of time, and are strongly encouraged to follow safety and sanitization protocols.
Retail businesses and indoor portions of retail shopping malls may open to customers, while following required mitigation requirements.
Bars and restaurants may reopen while following appropriate safety and sanitization protocols.
Etc.
