And what is the cost of this licence?
Irrelevent - you still need it in order to use a public highway. You can own a vehicle without paying VED if you wish - VED license is a requirement of using a public highway.
Therefore it's nonsense to say that VED isn't for using roads. It is.
What it isn't for is paying for road repairs etc, but thats not the same as saying VED isn't for the use of roads. It quite obviously is which is why in order for the government to legally exempt cars from VED they still needed to provide a zero cost VED License.
I thought you were a lawyer, isn't intrepreting law and guidance what you are best at
