So I have to believe you have not thought this all
through. I have breathed 10+wt% ozone on a
couple of occasions. I can still smell ozone, and
a lot of other things.

I'm sure I have not thought it through in the depth it
deserves,

Actually you probably have. Because we are straining at gnats here.

nor done any calculations, but I would suggest it is
obvious you have not done so either.

1. I did not say ozone permanently destroys your
sense of smell, as you are falsely attributing to me.
I believe it desensitizes it sufficiently to cover odors
when the generator is running and for a short time
afterwards. If the smell disappeared permanently, I
would agree the ozone had been working on the
odorant materials. In the case of mildew in a large
water damaged warehouse, without any forced air
circulation, I think the effect was on the employee's
nose, not on the spores.

You said:
And yet I've seen it be quite effective on a mildew smell
in a space large enough there is no chance it was really
removing the odorant.

Your express claim is that, not in your opinion, ozone could not
remove the mildew smell. "No chance" you said. In your example, to
which only you have the "rest of the story" you did not say that the
smell came back. Ozone is used in mildew remediation. You can
eliminate the smell with very little ozone, and as long as the stuff
never gets wet again, the *smell* never comes back. Even if the
mildew spores and dead "skeletons" might still be present.

2. You claimed that ozone could only desensitize the
nose to ozone (and imply that this is a permanent
condition.)

I made no such claim. I could smell sweat on stainless steel, when I
could no longer smell ozone. Your post implied that, again with the
"rest of the story missing", they did not smell anything of mildew
ever again:

Your statement of opinion.
So I have to believe the desensitization is a bit more
general than you think.

"General" seems to read as "permanent" in your "two paragraph"
response.

My mildew example was one where I believe the
desensitization was to something other than odor.
Ben's cigaret smoke example was one where he believes
the desensitization was to something other than ozone.
If you have some evidence for your claim now would be a
good time to cite it.

There are a host of companies that "decontaminate" used cars, using
ozone to counter, among other things, smoke odors... using only ozone.

There are a host of companies the remediate water / smoke damaged
buildings / structures, and where they don't strip it down to studs,
they use ozone to permanently destroy the odor (if not "sterilize"
it).

Insurance companies accept charges from these companies, and do not
accept them as permanently damaging their client's sense of smell.

Now I apologize if I have put words in your mouth, that you did not
mean to say what I "heard". Unless we are going to talk past one
another yet again, the last words can be yours.
