I'm lost on this one, guys.

Why should a station (just because they're low power, or DX) be privileged 
above us "commoners" to a second QRG for clear reception?

Good luck on this one now!

What is the difference in spectrum used if the pile is 500 Hz up, or 5000 Hz
up?

The spectrum used is dependent on the bandwidth of the signals and the
spread around a second frequency, not how far away the second frequency
is.......once it does not overlap the TX channel width.

There might be a logical reason I'm missing. I'm trying to understand the
"ruckus" about a 5 kHz split wasting space, when the same exact space is
used with a 2 kHz split or a 1 kHz split.

If the split is 5 kHz and the stations using that split have emission
confined within 500 Hz, they use an extra 500 Hz over single frequency. If
the split is 1 kHz, they still use an extra 500 Hz.  The use is at a
different spot, but still extracts exactly the same total spectrum from
other use.

If someone is at 7.005 and working simplex and most people have all
emissions within 500 Hz of width (+ - 250 Hz) they use 500 Hz from 7.00475
to 7.00525 kHz. If they listen up 500 Hz, they simply move that 500 Hz slice
up the band from 7.00525 to 7.00575 kHz.

If they move it 5 kHz or 100 kHz up the band, they still "hog" the same
total space.

I'm trying to figure out what people are trying to say, because it has
nothing to do with the split distance once it is all outside the one
transmit channel width.
