Why!? When masks are such a cool thing!?
Asking everyone to wear one for an off-chance that someone, somewhere, among the millions around you, might actually cough directly into your face, is the same as asking every man, under a threat of jail, to wear a condom every time because someone, somewhere might have HIV.
About the mime attached to this post: you pull out a meme from the internet as a scientific proof!? A meme where someone pulled those percentages out of their ass as a scientific proof!?
When you don't know what you are talking about, you shouldn't! A lesson made clear by Trump but you don't want to learn it.
That meme is to show you roughly the benefit of wearing the masks, don't get stuck in the exact percentages.
Please familiarize yourself how this virus transmits, you should have gotten a clue from your own person. Did anybody coughed in your face? This is not the most common way, and it's been described many times here or elsewhere but it's been like water on a duck's back. You spit when you talk among other things; when you cough it get's on object from where you can get it, sometimes quite far from the infectious person. What the mask does is limiting the spread of infectious particles from the infectious people. It limits a little your risk of taking it, but that's not the main goal. Although if you are disciplined it's a very good reminder of not to touch your face.
Comparing a mask with a condom is so far fetched that it shows again you didn't put any thought into it.

You should try to live for many hours at a time with an N95 (at least) or a PAPR, and a faceshield along with a protective gown, I would like to see how strong you will be. There is no comparison to wearing a simple mask for a couple of hours at a time, at most; yes, wearing a mask at the store it's inconvenient and my glasses fog up constantly but I do this to live with a clean conscious that I didn't infect others.
