That was a lot of keystrokes to say masks don't work, even the magical N95.
First, 5% of a virus getting through means viruses are still getting through, people are going to catch it.
Your paean to the N95 also failed to note the most glaring "hole" in the theory that they block viruses: the vent. They were designed for use in contaminated environments, to protect the wearer only, from dust and other large particles.
They vent UNFILTERED AIR that you exhale into the environment.
They make it harder for the wearer to inhale. They increase CO2 concentration in the blood while decreasing O2. They vent unfiltered, germ-laden vapor to the outside. They also concentrate microbes near the wearer's nose and mouth for constant rebreathing, causing pneumonia.
And the N95 box proudly states that THEY DO NOT BLOCK TRANSMISSION OF ANY VIRUS.
Only the incorrect model of "chainlink fence in sandstorm" was the basis of my explanation. This is an incorrect model and if you ever find yourself in a discussion about masks, you do not want to use this as a basis for discussion.

Completely agree with everything you said.

Also restricted breathing causes stress.
