Yes, ragweed is native, and it has its merits, but I think it VERY
unlikely that humans are capable of eradicating it. The reason it is a
nuisance is that it grows like a weed, meaning that it is capable of
moving in quickly on disturbed or waste ground that is produced by
human activity, just like introduced weedy species so. In urban areas,
there is no reason that we should favor a plant that causes so many to
be miserable due to the vast clouds of pollen it releases, just because
it happens to be native. If ragweed were an endangered wildflower I would
say leave it alone if it sprouts, but it can't hurt to make urban life
nicer by having less annoying plants around.
