The problem people have with your argument is not the existence of 5.1 surround sound.

Nor is it that the vast majority of households can’t afford a properly tuned surround sound setup instead of haphazardly throwing speakers around which arguably creates a worse experience than stereo.

It’s that the Dolby implementation requires publishers to license it and pay for an unstoppable ad that plays before every session, while benefitting only the petit bourgeois.

Notice how you reverted so quickly to your capitalist brainwashing. May be a good inspiration to see what other ideologies have been implanted into you.
