I mean sure nature has no obligation to not have a unfalsifable particle, but you wind up in weird places, like, there exists a distribution of dark matter that explains the poltergeist that knocked over your coffee cup last week.
If there would be a distribution of dark matter that explains the poltergeist, we could measure that distribution of dark matter.
We can measure the mass distribution on astronomical scales. We "see" the dark matter. Just not with light.
