There is at least one absolute, and you refuse it.

That's potentially the case, but in actuality Foveon sensors lose more photons than do Bayer.

In actuality they lose almost none, can you truly disagree that most of the photons hitting the sensor end up in the sensor at one depth or another?.  It's the processing that matters.

Bayer filters don't in fact lose 2/3

In discussions in photography there are a lot of things that are more subjective than not, because there are so many moving parts - things like color accuracy for example, when people could use any number of options for processing RAW, all of which have their own take on what color means.  All of that fed into monitors that may more may not be calibrated, may or may not be calibrated well. Then viewed by eyes that may will interpret color slightly differently one person to the next...

However in this world of subjective reflected dream capturing that we all take part in, there is at least one physical absolute that remains true now and forever.  By definition, a bayer filter does in fact block 2/3 of all photons from ever reaching the sensor.  That's just how filters work.  When talking about photons it does not matter that humans happen to "see" luminance more clearly, it's a matter of the most basic physics, a colored filter letting through some wavelengths and not others.

If you can't admit that simple and obvious absolute, what are we to make of the rest of your positions?
