“The man who was once starved may revenge himself upon the world not by stealing just once, or by stealing only what he needs, but by taking from the world an endless toll in payment of something irreplaceable, which is the lost faith.”

As quoted in Art of Communicating Ideas (1952) by William Joseph Grace, p. 389

The Economic Tendency of Freethought (1890)
Context: A man won't steal, ordinarily, unless that which he steals is something he cannot as easily get without stealing; in liberty the cost of stealing would involve greater difficulties than producing, and consequently he would not be apt to steal. But suppose a man steals. Today you go to a representative of that power which has robbed you of the earth, of the right of free contract of the means of exchange, taxes you for everything you eat or wear (the meanest form of robbery), — you go to him for redress from a thief!

UTI interview (2004)
Context: The law about what is stealing is very clear. Stealing is taking something away from someone so they cannot use it. There’s no way that making a copy of something is stealing under that definition.
If you make a copy of something, you’ll be prosecuted for copyright infringement or something similar — not larceny (the legal term for stealing). Stealing, like piracy and intellectual property, is another one of those terms cooked up to make us think of intellectual works the same way we think of physical items. But the two are very different.
You can’t just punish people because they took away a “potential sale”. Earthquakes take away potential sales, as do libraries and rental stores and negative reviews. Competitors also take away potential sales.
