It is true, however, that Singapore is now having a "2nd wave" of infections after stopping extreme self isolation, so they are having to return to those policies.
As no one has found an effective treatment, we are left with just two options.
1. herd immunity, without a vaccine, may start having an effect at 60% of folks infected. The ugly part of that is 336 M x .6 =~ 202 M cases X 3.4% (taken by dividing today's case count into today's deaths)=~6.8 M deaths.
2. a working vaccine. There are 2 candidates in emergency human trials. Cross your fingers and toes.
Don't you trust Dr. Fauci? Just the other day he stated that the most recent and best estimate is about 60,000 deaths, in total, from Covid-19. Never does an entire population (100%) come down with any particular disease; 15% is much more common. Even with Covid-19, coronaviruses have been around for quite some time so anyone who's had one will most likely possess partial immunity to Covid-19; this is one reason why the vast majority of those who contract the virus have only moderate, mild, or no symptoms. Case fatality rates like the 3.4% vary wildly from day to day as well as from locale to locale; they are the absolute worst number to extrapolate anything from statistically.
It's very easy to panic. I understand that. Everyone should take a deep breath.... hold... and let it out slowly. Try to calm down.
So you assume just because the disease shares the word "Coronavirus" that people would have some immunity to Covid19?
That would be dead wrong thinking.
Well, you can make that claim, but where's your evidence?
Here's mine. Dr. Martin Dubravec MD, an immunologist based in Cadillac MI, wrote this:

Most people don’t get COVID-19. Why?
Testing of high risk people (those who most likely would get COVID-19 due to exposure to confirmed COVID-19 patients or travel from high risk areas) reveal that 90% of patients are testing negative, i.e., they have not evidence of disease. Why is that? Most likely, these patients have pre-existing immunity to the virus from previous exposure to COVID-19 or due to cross-reactive immunity from being infected by related Coronaviruses. Many people have stated that they suffered symptoms of Coronavirus earlier this year. Due to a lack of testing, many people most likely have had exposure to the virus; they have developed immunity to it.
This is why the concept of herd immunity is so important. With herd immunity, significant amounts of the population will have exposure to the virus and become immune to it. They are no longer able to spread the virus as their immune systems kill the virus before it has a chance to grow and multiply. That individual then becomes not a source of viral spread but a source of killing the virus. The virus has nowhere to go and it disappears.
Notice that the immunologist says people who've had "related Coronaviruses" may have "cross-reactive immunity" to Covid-19. It may be partial immunity or even full immunitiy.
