I love it. Libertarians and similar always like to say "communism sucks, can not work, can never work, is a completely broken model"... when the reality is that 1) they _dislike_ the model (which doesn't make it broken), and/or 2) that communism, like many systems, works well, until annoying corrupt humans wanting money, power or both start interfering with the ecosystem.
The second point is entirely accurate. It's one of the major factors that makes communism, socialism, untenable in many ways.
What's hilarious / frustrating is how these same people think that humans in a libertarian utopia won't be corrupt, won't want for money and power, and as a result, "Sure, remove all regulation - the market will get more efficient! It certainly won't end up like the railroads in the 19th century, or something out of an Upton Sinclair novel!"
