I'm afraid you don't get it at all.
1: Most people will simply not open a command line. They are, in a sense, afraid of it.
2: Where will they "get" this pgp? A google search does not supply a single clear answer.
3: The command you entered doesn't do much to integrate it in outlook, or whatever email client they use. How would they go about doing that. More importantly, if they actually do manage to run that command, how would they know it's not actually set up in outlook? They installed the program, didn't they? So it should work.
And the following are of particular importance:
4: How do you mean email is insecure?
5: Who would be interested in my email anyway?
6: How does this make my email more secure? No one I know uses this GPP or whatsitcalled (and why the feck can't they name it something normal)
Really, this might be very logical to you, easy to grasp and interesting, but about 99% of the people using email, do not share your view. They are simply computer users and if something isn't completely installed through an official looking installer like InstallShield or Wise Installer where they only have to press [continue] and maybe enter their name in a box, it's impossible to grasp for them. This isn't strange. Computers don't work as regular machines do, where you can see how they work through gears, cogs and belts, and even then most people don't understand those machines. Computers are like... "geeky stuff". They don't understand it, and they don't care to understand and that's okay because as a user it's not your job to understand. That's the programmer's job. You don't need to know how to build, calculate and design a car to be able to drive it. You just need to be able to use it. It's GM's job to design and construct the car in such a way that it's usable and that the airbags only deploys when it's needed.
The other way around, you would probably not be interested in learning a lot of stuff about fashion, how the industry works and how certain fabrics can be used in combination with colors, shapes, filler materials and everything that comes with it. I wouldn't blame you. You also don't expect this knowledge to be necessary to walk into the nearest clothing store to buy a few T's and jeans. Perhaps you would be interested in how to calculate astrology signs for people? In a similar way that those might be subjects you wouldn't be interested in, they aren't interested in the workings of a computer.
As a closing:
You cannot change all the people in the world. Don't try to, because you will only get frustrated. You can however learn how most people think. Learn about ergonomics, learn about 95th or 98th percentile thinking patterns. See what people are willing to do, and most importantly, what they are not. Apply this knowledge to your programs and projects, and always remember, if anything in your area of expertise or interest is clear and logical to you, it most likely isn't to anyone who doesn't share this expertise or interest.
