From the paper:

Deutsch claimed to 'prove', via decision theory, that the 'rational' agent who believes she lives in an Everettian multiverse will nevertheless 'make decisions as if' the mod-squared measure gave chances for outcomes.

This must a bad wording, or something, otherwise why does a "rational" agent who does not believe "she lives in an Everettian multiverse" can still confirm the Born rule experimentally time after time?

The proof does not address rational agents who do not believe they are in an Everettian multiverse. They would have other reasons for using the Born rule.
