You're right, but way over the top added drama since the tiny bit of extra
smoke doesn't matter as "dramatically" as you're trying to make it matter.
The op isn't asking to use 4-stroke oil all the time but just in a pinch.
Say you're miles from a hardware store and you run out of two-stroke oil.
You shouldn't have to give up and drive fifty miles (which causes even MORE
pollution) just to get the "right" oil when the "wrong" oil works fine (see
all the references I already quoted which tested them all).
The tests I reported elsewhere show that the 4-stroke motor oil used as
2-stroke gas/oil mixture did burn less cleanly by a tiny bit, which if
EVERYONE did, would add to pollution. They also showed almost no difference
in cylinder/piston wear and the same with combustion deposits.
The verdict is that, in a pinch, almost anything works as well as
two-stroke oil, but most people would try to keep it on hand.
You're being too dramatic given there's really no major difference, sort of
like if you used brown sugar in a chocolate cake versus white refined sugar
or regular salt instead of kosher salt in a vegetable dish.
There is really no need for drama.
The teeny tiny bit of extra pollution from using a chainsaw with the 'wrong
oil' in an emergency is nowhere near the pollution of a single campfire.
