mean that in GIMP's vector import dialog you specify a scaling ratio (X
Ratio / Y Ratio) of 0.50 ? Then of course you are going to get some aliasing
(just the same as if you scaled a raster image by 50%), but the overall result
should closely resemble what the original SVG document looked like . . . at a
50% zoom level.
Remember that in a vector document "pixels" do not correspond to "on-screen"
pixels but are a physical unit of measure.

If you are taking the 2048x2048 image and scaling it to 80x50 then that is a
ratio of less than 10 percent and of course the result is probably going to
look like a blurred/aliased mess of pixels. Now if the original SVG document
itself had a document size of 80x50 (which is separate from the size of vector
elements in it) then GIMP should be able to import it fine.
Numbers may not lie, but neither do they tell the whole truth.
