1) Depending on the speculation of which "expert" you choose to believe a lot of people OR most people will become infected.
2) Depending on the speculation of which "expert" you choose to believe some people OR many people infected will die.
Since, according to the "experts", there's apparently no 100% effective precautions I can take to protect myself I'll just have to wait to see IF I get infected and IF I die.
The same “experts” predicted a new ice age in 1970, no doubt.
It is more complicated then that. After you survive the virus. You are still able to become reinfected. So a weak immune person will get it again quickly. Even if they survive the initial infection. So what will become crucial, is delaying everytime you get infected as long as possible.
4.8% fatality rate.

Even though no 100% effective precautions or measures exist, it make sense to wear a mask, etc.: 1) To reduce the viral load on your immune system. Maybe not to zero, but very low. If low enough, the immune system might contain the infection with no symptoms or further transmission. 2) To attempt to delay infection until a vaccine and/or antiviral is available or the virus mutates to non-viable status and disappears.
Similar arguments can be made for use of supplements such as NAC and monolaurin.
To take no precautionary action whatsoever is not rational.
