Is plagiarism an addiction?

In a post titled 'Tis the Season, for Student Plagiarizing , Anastasia Rubis writes:

It means that many students have been getting by for a long time by Googling, and cutting & pasting. It's a habit. Let me go further: it's an addiction. According to Merriam-Webster.com, an addiction is a "persistent, compulsive use of a substance known by the user to be harmful." Students are addicted to a substance, Internet content, and compulsively appropriate it into their essays, even though they know it's a bad idea and they will get caught.

If Internet plagiarism is an addiction, then reporting a plagiarizer to the dean and flunking her is ineffective, because it doesn't address the dependency.

IPBiz does not think so. Nor did several of the commenters. One can rely on internet content and cite the source.
