They govern over non-citizens as well, e.g. over residents and visitors to the geography where the government has/claims sovereignty, but the non-citizens tend to get fewer rights than the citizens.
I understand your distinction I think...however the parent comment (about abolishing citizenship) is still (on the face of it) advocating anarchy. Degrees of citizenship must exist always, even when the "official" line is that none do - as you state even in the case of "equal citizenship" there is still the degree of citizen, and non-citizen, so really you can never remove that (without also removing government).
Being in the position of abolishing _birthright_ citizenship is a very different stance than abolishing the practice of citizenship outright. I think you are speaking of "second class citizenship" e.g. immigrants or temporary who do in fact benefit from and are expected to follow the laws of the land, but who do not get e.g. voting rights.
I.e. perhaps the view is the equalize all practical citizens under the law (which is possible but difficult to do wrt to land ownership and community security, especially).
