Yeah, that part was laughable. No one in Numenor has seen an elf in 100s of years. One elf shows up, and all of a sudden the trade unions think they'll lose all their jobs to her
On the other hand the show's attitude is overall middling-positive about the elvish imperial state - and on top of that Galadriel's multi-century War on Terror is ultimately justified.
I don't think the story is coherent enough to be making a real political statement, even if a few scenes gesture wildly at a few vague (and contradictory) political ideas.
