Explain why Hobbes would argue that you ought to obey a law like not stealing, when in this case you know that you can get it away with it.

When in this case refers to free public broadcasting for TV and Radio.  How many persons enjoy the media and do  not contribute to it but say that someone else can do it.  If you can afford to support the programming, should you not make some contribution?  With these stations there is no obligation except your good will to see then continue.  How should we view persons who use the media but let everyone else pay for it?  Isn't that confirming some of what Hobbes is saying about the selfishness of human nature?
