Consider a view of current events which people on the internet generally support, things like "stop internet censorship", "free julian assange", "TSA are thugs", or whatever is currently popular.
Then picture a person performing an elaborate protest which attracts media attention.
But somewhere on his clothes or the placard he is holding, or somewhere else, there is a qt code which links to his bitcoin address-and he ends up collecting donations by people who are happy that he staged the event.
Since popular opinions on the internet are generally good things, anticensorship for example, the result of this idea taking off could be more protests about things the internet supports. "Armchair activists" who do not want to spend their time or risk their career supporting certain causes, could indirectly do so by this method.
This is exactly the sort of economically meaningless idiocy Bitcoin needs less of.
Completely aside - OP: forget politics and go eat moar textbooks. You're not of an age where your political opinion adds value.
