If I go to an Apple store and decide I can pick up an iPad and get out, because I've been nice to everybody and I deserve it, similar things will happen, starting with "Excuse me sir," verbal arguments, guards, armed guards, and (if I decide to defend my right to my iPad with armed force) eventually a shoot-out match.

So, we could equally say that there is implied violence in every transaction. (Well, yes sometimes the violence is leased from the government, which will happen if I bring my armed thugs to raid an Apple store. And I'd consider that a good use of the government's resource.)
