Add existing Google account without accepting Google Play agreement

I've received a new Samsung Galaxy S5.

I want to add my existing Google account to the phone, to be able to use Gmail and my calendar. However, when adding my account under Settings, the phone requires me to accept a bunch of legal agreements, including one about Google Play and its billing functions.

I don't want to be forced to accept a legal agreement concerning a service I don't intend to use just to access my email and calendar data.

How can I get around this?
