The last daughter of Krypton!
(Aw now I made myself sad.)
Well. Yeah they can. If they’re Kryptonians on Earth. It’s just that there aren’t any more Kryptonians (in pre-CoIE DCU).
And I bet Supergirl has to take out the trash and do other chores just like a million other daughters, so yeah, they can do the things Supergirl can do! Like going to the library, or taking care of a horse.
