I think that the elven Art too alters the world, but it still remains "good", as noted above - they weren't "bulldozing the real world, nor coercing other wills".

Well, they weren't 'coercing' perhaps, but they were controlling - there was no 'stain' on Lorien. We can only take this to mean no parasites, no fungi, nothing to mar its 'perfection'. As I said, the Lorien we are introduced to in LotR is a 'hyper-natural' place, almost a higher state of nature, a glimpse of Arda Unmarred, yet there is no sense that it has been 'forced' into being that way. We don't even question how it is that way, we simply accept it. It is not an 'alteration' of the primary world but rather another 'state' of it.

Once Tolkien introduces the story of Galadriel's desire to rule a land free of death & corruption & her use of Nenya to bring this about, suddenly we are dealing with "bulldozing the real world,", because she is not allowing natural processes to occur. She will not allow death to enter in to Lorien. The trees are not allowedto die, parasites are not allowed to exist, because she does not want them to. Her suppport of the Ringbearer is a surrendering to nature, an allowing it to be. Only then could she truly be herself.

Their 'magic' is Art, delivered from many of its human limitations: more effortless, more quick, more complete (product, and vision in unflawed correspondence). And its object is Art not Power, sub-creation not domination and tyrannous re-forming of Creation"

This may describe the Elves at their best (Vanyar & Teleri), but I can't see that it applies to either the exiled Noldor or the Sindar. Certainly his condemnation of them as 'embalmers' would seem to contradict this statement.
