If a BRS system were available factory installed at a

Offering a BRS system standard on all of their airplanes is

in the world.

Yes you're probably quite right about the Cirrus BUT in a
Cirrus you might well have wife and kids along for the ride.
The fact remains that the majority of DG customers do not
specify the NOAH system; it's actually relatively cheap
compared to the new cost of a DG808C or DG1000x. Why is
that?

Maybe people think that the NOAH system is a half baked solution. Cirrus and Phoenix think that BRS systems are important enough that they make them standard and a significant part of their marketing.

The NOAH system is far from "half baked". DG actually developed a system that works, and they are the only ones that have for a glider. Approximately two thirds of the non-motor gliders sold, have sustainers engines where the BRS would go, hence the NOAH. This is an emergency assist. The chance of needing such a device is as rare as needing to jump, yet DG stepped up to the plate and designed and tested a solution, that is affordable (about 4,000 euro before installation). Comparing Phoenix and Cirrus aircraft, with their marketing, design, customers base, and funding sources, to gliding is with all due respect "half baked".
