Everything you said is technically correct, and helpful to some people, but it doesn't change the fact that most users opt to simply disable automatic updates in one fashion or another. Manual updates, and "download-but-don't-install" are both different from the Chrome example, and in both cases, will cause IE to not be immediately patched for all of its users even once Microsoft pushes an update for it.
And, if I may push back just a little bit more: "install an SSD" should ideally never, ever be a serious solution to the problem of software updates. I'd like to think that I'd have the good grace to be completely embarrassed if I ran a software company that had advocates telling other people that my long update process could be "solved" by installing an SSD.

Most people disable auto updates? Do you have a reference for that or is that just your personal anecdote? Most people and PCs I've been auto update. Normal users don't even care to take the time to find out if they can be disabled.
You can only force users so much. Installing updates and restarting is a default and people who go out of their way to prevent it deserve to take some responsibility, it's their machine after all, not Microsoft's nor yours. If Windows forced everyone to update and restart automatically without a way to turn it off, a lot of people will raise hell over it. Some people don't like even browsers autoupdating under them.

Not that you're technically wrong.
