Your analogy undermines the point you seem to be making, given that renting is, by definition, not purchasing.
More so you look at a rental car from afar, and using your own mediums make your own exact copy, which you then use for a ride.
Except, you incur quite an expense making your own exact copy whereas copying some bits costs you such a low number that it approaches $0
Isn't it a replica of the rental car in the analogy?

In the UK there's a law covering this specific case.
