You need SOME amplifier element; just logic alone would not do.
Neon lights for logic certainly would be possible, but neither convenient nor
reliable in my mind, since the difference between ignition voltage and burning
voltage
is not that big. Diodes are MUCH more convenient AND a lot less expensive
than Neon lights.

Hi
Neon lights are good enough. They can make amplifiers
as well because of the negative resistance. Something
like a tunnel diode does. Many have made logic systems
with neon lights only, during the sixties. One of my
class mates made a neon light adding machine so it
can be done. I don't recall for sure but the
difference between the run and the fire voltage
of NE2's was something like 40V and 60V as I recall.
I could be a little wrong on these numbers.
