I did not say that it is the same as destruction of property. I said that it is an illegal activity that has the same effect on my life as destruction of property. I'm saying this because some people seem to think that it is ethical to pirate software, or at least nowhere near as bad as destroying property.

There is also a difference in degree in opening a bakery without permits. This doesn't nearly give you as much of an "advantage" as a pirate giving it away for free. I can't think of anything that would give you a comparable advantage with physical goods.
