How much higher are you willing to go? Where does herd immunity start, maybe at 70% immune? With a 3% death rate (optimistic with those numbers) that gives you about 7 million dead. Absent a vaccine or effective, cheap and widely available antivirals then we could all stay at home for 1.5 years. That might cost more than we can collectively afford. That's probably a no, which leaves aggressive quarantining and contact tracing as likely the only other way to prevent that exponential explosion with its dreadful potential for death.
