I don't accept the argument, but as a thought experiment lets go with it. So motorists pay for the roads and for trains - so what? I pay lots of tax for services I don't use - or perhaps someone else doesn't pay for something I also use (public libraries for example) - but so what? We pay tax and we may use some, all or none of the services provided - it's just part of the bargain with the state to create a civil society. Just because you've paid tax (greater or lesser) doesn't give you more or less access to services as a citizen.
