FURTHER UPDATE (Mar 2, 2010 4:50 PM): In what has now become a world-class blogalicious cock-up, commenter
Albert Esplugas reports that he cannot reproduce Hans's figures. And I couldn't either, at least I couldn't yesterday. But now I can again. Not sure what is going on. Anyway, be wary of any reference to the number of Google results that some phrase or other supposedly returns. I'm clearly out of my depth here.
RETRACTION (Feb 25, 2010 2:12 PM): Commenter Hans
has found a serious fault in my Google phrase search methods. I tried a "* is theft" search and noted the top responses that came up in the auto-complete box. But Hans simply typed in some other phrases and found the following:
"sex is theft": 40,400
"love is theft": 57,000
"everything is theft": 111,000
"government is theft": 10,300,000 (!)
This will teach me to post after my bed-time. Although I do suppose the fact that the numbers seemed plausible to everyone but Hans (and others who were dubious but who didn't bother to comment) says something?
Original (and now basically useless) post appears below:

In recent days, while following the raging
inflation debates, I've noticed the phrase "Inflation is theft" in blog comments a lot. I remember that Ron Paul had a hand in popularizing the concept during his 2008 presidential run, as he criticized the United States's fiat money and Federal Reserve systems, which he argued lead to too much savings-munching inflation (which he considers theft).
It got me to thinking, "What
else do people think is theft?" I'd heard of both taxation and property being equated to theft, even though the partisans of those views occupy opposite extremes of the economic policy spectrum. I wondered if other interest groups had hit upon the idea of branding the thing they didn't like as "theft."
So I did a Google search on the wildcard phrase "* is theft" and was a bit surprised by what I found, though I probably shouldn't have been. The top Google result, by far, was for "
Piracy is theft," with 2.4 million results. Not high-seas piracy (though there were probably a few of those in there), but piracy in the sense of illegal downloading and/or copying of digital media, especially movies, video, music, and software. All by itself,
Piracy accounted for 79% of the total results for the top 12 phrases combined. But the digital publishers, represented by powerful trade groups such as the
RIAA and the MPAA, don't stop there. The terms
Copying,
Downloading, and
Sampling are also in top 12, and together these four supposed theft-equivalents account for almost 80% of the total results.
Another surprise was that the phrase "
Theft is theft" came in second, probably owing more to its rhetorical use by the digital publishers than as a logician's example of the
law of identity, but I decided to give the logicians credit anyway.
Compared to the RIAA-MPAA juggernaut, the economic and political ideologues are a rag-tag bunch when it comes to applying the "theft" label to things they don't care for. The Libertarians (
"Taxation is theft") are the best of the rest, with the Pacifists (
"War is theft"), and Anarchists (
"Property is theft") not too far behind. The Communists ("
Profit is theft") were a distant fifth, followed by the Academics (
Plagiarism), the Squatters (
Rent), and Ron Paul's Goldbugs (
Inflation) coming in at number 11:

The blue bars show the actual counts, while the yellow line traces the function of the trend line specified in the equation. It's a classic
power-law distribution of the type that
Wired's Chris Anderson wrote about in his 2006 book
The Long Tail, where a single market leader grabs the vast majority of market share and is trailed by a long list of lesser players:
