England has a whole bunch of legislation to prohibit activities that are not theft because it turns out that sometimes we care about other things. TWOC is an example, "Taking Without Owners Consent", because it turns out that it's also very annoying to have people take your car and then drive it somewhere and abandon it for a laugh ("Joy riding"), compared to them say, stealing it to ship abroad, break into parts or just to set it on fire.
Insisting that it's all theft gets us in the same muddle as when we decide that holding up a protest sign is terrorism, or that a billion dollar bribe is speech.
