Much of northern europe has a "freedom to roam" making this explicitly legal and acceptable (within certain limits). Nobody is saying that all law should be based in property.

Well since we're talking about intellectual property, quoting is an obvious example. Often in debates (esp. Political) people will "borrow" their opposition's words against their will with the intention of making them look stupid.
Most science involves working off other's ideas, without the ideas originator's consent (but attribution is required).
> What are the general responsibilities of society?
That's a heavy philosophical question, and answers will vary. Usually involves ensuring the administration of justice and having a monoply on violence. Sometimes providing basic neccesesities is included. People often do include enforcing physical property rights here (i have never heard of people including intellectual prop rights, although there probably are people who feel that way). In some communist states, the right for every person to have a job is assumed, which i suppose could be taken to mean a responsibility to make people money. In capitalistic socities there is no garuntee of business success; the fundamental principle being either you should make money on your own merit or go out of business. At most there is a responsibility to create a fair marketplace, but what that means varries a lot.
