Its not!!!. And it says something about you that you cannot understand the difference. Now check again a little more closely. Wherever I made an assumption , I have indicated it. In your enthusiasm to find fault, you fail to see the woods for the trees .That’s just a lot of unnecessary words to say, I have no idea what I’m talking about and make it up as I go along.
In the current situation, no information is better than bad information. Bad information tends to be the sort of guesswork you are posting.
I am agreeing, that aerosol formation from normal tidal breathing expells viruses. The Study suggests the numbers of 100K per hour . These will be somewhat directed, but the plume will be dispersed within 0.5 metre. It then becomes broadly isotropic ..or at least wind born. This is why a greater distance is preferable.. volume cubes
Coughing and spluttering will produce a greater local concentration ..or viral load. Fortunately the range is limited.
