So why isn't prepay valid for all stations out to the end of Zone 6?

Because prepay is only available on National Rail for sections of line
where Underground fares apply; essentially this is any section that
could, as an alternative, the passenger could travel by LU services.

Thanks. The more I hear about the restrictions on an Oyster the more I
believe it is a total waste of time & effort.

This isn't TfL's fault - they have to go and negotiate with each
individual TOC to allow Oysters to be used on their lines, IIRC.
