I think the point is that msellout feels (please correct), and I'm inclined to agree, that the assumption that cars are entitled on highways but cyclists are not is wrong.
There is probably more benefit in having less cars and more cycles than the converse.
It rather sounds to me like he just wants all cars off the road, and I'm not sure how you could arrive at a different conclusion without applying liberal amounts of conjecture.
Personally I think he was using hyperbole; countering the suggestion that cyclists shouldn't be allowed on the road and questioning the assumption that the solution to cycle-auto conflict had to fall in favour of the car.
