I can't count how many times I have to explain to people that etymological roots of words are not a foundation for an argument. The term "Piracy" was adopted by movie studios back when it wasn't really illegal... the same ones who also tried to make used media illegal (and eventually succeeded in a way).
Your Shakespearian example is very clearly theft
Except it's not, nor was it ever. Here's my metric. Anyone more property-focused than Adam Smith is wrong by default. If you're more capitalist than the founder of capitalism, maybe you have a problem. It's like Marx looking at someone and going "OMG is he too communist for me".
