There is just as much evidence these criteria are true as there is for dark stuff - currently none.
Not actually correct. The bullet cluster (see Wikipedia) is extremely hard to explain without Dark Matter. This collision between two galaxies has effectively separated he normal matter from the dark matter so we observe a gravitational field bending light where there is no normal matter. Without Dark Matter you are left with the extremely hard task of trying to explain how a gravitational field can exist where there is no matter.
