Hello again spacevisitor,
As you know also, Professor Nasri Iskander makes that statement after the findings of tobacco during the repair of the damage of the mummy of Ramses
II at the Museum of Mankind in Paris.
Yes, and he mentions that it's a possibility. He never claims it as fact. Still, his possibility makes more sense than a non-existant trade route of
that time.
I believe there is a simpler answer, overall. Taken from the Hall of Maat:

Concerning Nicotine.
Whilst nicotine is an abundant alkaloid in tobacco plants (Nicotiana tabacum) it is also present in relatively small amounts in some Old World plants
including Belladonna (Atropa bella-donna), Celery (Apium graveolens) and Jimsonweed (Datum stramonium).
and
Nicotiana fruticosa is also known to grow in regions of China, where it was domesticated and was known by its Chinese names “cay-thüóc-än” and
“yen-yé”.
and
Additionally a species of tobacco, Nicotiana africana, has recently been identified as indigenous to Namibia in South West Africa.
Concerning cocaine.
Cocaine is produced in quantity exclusively by Erythroxylum species native to South America [8 & 35 - 37]. However the genus Erythroxylon contains
over 200 species distributed throughout the tropics including the Americas, Asia, South Africa, Madagascar and Australia. Some of these species
produce cocaine although in much smaller amounts than in the South American species. [38 - 42] E. brownianum for instance is a species native to South
Africa which produces 400ppm (parts per million – equivalent to 0.4mg/g) cocaine in its leaves. [40] E. monogynum, red cedar, is native to India and
contains up to 400ppm cocaine in its roots. [40] The shoots and leaves from this plant are also edible. It is possible that the Ancient Egyptians
could have had access to these species of plant or even that there were related species present in Egypt that produced cocaine in sufficient quantity
to account for the amounts identified.
As you can see, there is no need to cross the ocean for only 2 trade goods when they could get what they needed closer to home.
Despite how it came to Egypt then and perhaps we will find that out someday, why is it so absolute unacceptable for the Egyptologists?
Probably because there is no evidence for transoceanic trade for coca and tobacco. Where are the remains of SA coca plants or tobacco plants in Egypt?
Even the simplest items between cultures would be traded. Where are they? Who is the seafaring culture during most of the OP's timeframe?
If these and many other questions could be positively answered, there might be an argument for at least a possibility.
