I think you misunderstand the purposes of taxes and duties. They exist
to raise revenue, not to be fair.

The purpose is to raise revenue. That doesn't exclude the possibility of
the tax being fair. I don't see why a pensioner who does 3,000 miles a
year should pay the same road tax as a sales rep who does 100,000.

Governments use taxes for social engineering purposes; for modifying our
behaviour. If all the tax was on fuel people would drive less, and more
economically, which is just what they want for various reasons.
