I sort of like it because I think it offers a much more realistic depiction of how yukkuri would suffer if they were real; it would be apathy, not malice, on the part of the human race that would be the source of their problems.
Well I always said it, those ultra loving folks and the abyusers folks in the stories are only a minority in the yu world, the majority are probably average joes that don't mind yu's much and as much act to them like any they do to any other animal. If they are cute and nice they may adopt them, if they are wicked and pest like, they may call the exterminator or animal control, if they aren't interested at all they just walk away.
if they go to a yukkuri doctor they probably help them because that mold would dangerious to pets as well, though they may just wined up getting squished
