That's a very fair point. My only counter to it is that us geeks will spread the word that using Chrome in incognito mode is quite effective.
Ctrl-Shift-N is quite fast, and Google is pushing Chrome very hard, and us geeks are called on for tech support quite often.
I think your honesty thought will win out most of the time, but not always. People like a free lunch and sticking it to the man, especially if they have the tools to do it very easily. We'll see.
