I'm not sure your (or his) argument actually addresses popular beliefs. Two points:
Reductionism has been proposed not (merely) because it is intuitive, but because it is supported by the evidence. Starting with particle physics, you really can infer chemistry, thermodynamics, fluid mechanics, solid mechanics, heat transfer, and so on - and you can make correct predictions about when the assumptions used in the latter will break down. (For example: when the channels of fluid flow are comparable in size to the particles.) This is just as would be the case in a reductionistic universe.
Eliminativism is no more implied by reductionism than amorality. If you think that rainbows don't exist once they've been unweaved, you're making a mistake that has nothing to do with science.
I'm not sure your (or his) argument actually addresses popular beliefs.
I still think it relevant:
ad 1.: that might be so, but it's not all there is to reductionism, at least according to this or that attempt.
ad 2.: that might be so, but it's nonetheless a theory people rather easily catch, along with reductionism. For example: If you take reductionism for granted, and some entity does not easily fit it, then you are seduced into eliminating that entity.
