That's actually not true:
https://www.who.int/emergencies/dis.....w-to-use-masks
If you are sick, you should wear a mask as it prevents you from spreading your germs through microparticulates. It's less to protect yourself and more to protect other people.
Wearing a mask is also recommended if you're at home taking care of someone who is sick with the virus during the period in which you are actively taking care of them.
N95 masks should only be used if you are going to be in an at-risk environment during a long period of exposure, such as if you're working in a medical care facility. Telling people to only use this type of mask is a very dangerous proposition as it takes away critical equipment away from healthcare workers who need every single little bit of scrap they can muster.

but if you have the virus, or anything in the orthomyxoviridae family, or just something like staph that almost everyone carries around, a cotton mask or even silk, and especially the surgical masks that people have won't stop anything.
it has to be a N95 or better respirator, to stop a virus. and I am aware they are rare and expensive, and only last about 5 hours.
if it isn't properly sealed to your face, and made out of a material that can actually stop the microscopic entities, the infection can flow right through it, or around the edges. "it's better than nothing" in the same way a piece of plywood would be for stopping a .50 BMG.

A surgical mask is used to keep stuff in you to be propagated into the wild. It's used to catch particulates in which the viruses and bacterias reside, stay on surfaces and are spread around. It's extremely rare for any virus, though not quite as true of bacteria, to just exist outside of a carrier substance. Catching that substance - in the case of covid-19, that substance being sputum and other mouth/respiratory fluids - is more than enough. Hence why surgical masks are suggested for people who are sick who don't want to spread it around.
An N95 is overkill for you to use if you're sick as it made to filter air coming in first and foremost. That's why you don't see surgeons in a surgical room wearing those; since the operating room is sterile with positive pressure, they wear a surgical mask to keep whatever is in their body out of the surgery patient by putting a stopping barrier between their mouth and nose and the rest of the environment.
However, you will see nurses and other hospital workers wearing N95 masks to protect themselves from inhaling/breathing in infected particulates in the proper circumstances.
The smaller mesh of the N95 means that the negative pressure created when breathing in within the mask will keep the particles containing viruses, which COULD be pulled from infected substances are stopped at the mask level instead of passing through.
All of this is why healthcare professionals are BEGGING people to stop buying N95s pointlessly, so that their personnel can have the protective equipment they need which is rare at this time.
What you're suggesting is closer to using Chobham armour to protect yourself against a 6mm airsoft plastic .18g airsoft BB fired at 250 FPS.

surgical mask are made to stop things 0.1 µm wide, all of the Orthomyxoviridae are a tenth of that width. they're made to stop things getting out not things getting in. and really the issue is people wearing handmade cotton masks, with a distance of hundreds of times the size of a virus between the fibers. ignoring the space on the sides of the mask.
so 6mm bbs, and that diamond expanded metal mesh with 2-4 CMish holes.
did I mention at any point that the fur boi up there is cute AF?
