I don't disagree. If a corporation has civil rights, they're akin to being a person/entity in which those rights are guaranteed aka citizenship. Some might argue that America is a "corporatocracy" for this very reason.
Plenty of rights are conferred by merely being within the borders of a country, regardless of citizenship status. You can be a tourist or even an illegal immigrant in the US and have the right to habeas corpus or the right of non-self-incrimination, for example.
Talking about elevating corporations to be on par with citizens is a fascist idea, which is absolutely adjacent to corporatism.
A key tenet of fascism is protecting corporate interest and power... but okay.
