To be even more specific - you can only ever describe something by a function, and you have to supply a state in order to get a singular result. In physical space, the state we provide to get a result of any particular "object" is time. More simply: you can't describe any specific table with any meaningful properties without specifying the time in which you're observing the description. Every "thing" is just a transient state of being for at least one, if not millions, of variously interactive processes.
Of course, none of that is relevant to how useful it is to be able to reduce "state" down to the singular (and mostly "invisible") property of "time". It's just that while you are technically correct that the article did not 'remove state', it's only as technically correct as saying a banana is a "berry". In the vast majority of use cases, including teaching people the value of something, the specification is a difference without a distinction.
