I'm still with RichM - note his apostrophes. You can name a dialect 'standard English' but it remains one of many standards used to give clear meaning within a subset of an English speaking culture. SWE is a dialect which is accepted by many as a good communication medium in a world which reads newspapers etc. But it changes every day.

Standard English on a mobile phone is rather different but still one of many non-unique 'standard English's'.

American dialect is a non-unique standard English. So is Estuary English.

Naming something 'standard' is not establishing that the standard exists.
