Do you know anyone who grows their own tomotoes? I bet you do.
Now. Tell me ANYONE who grows his own tobacco.

Put that in your pipe and smoke it.
I've seen forums where they discuss how to grow it and cure it and where to get seeds. I've considered doing it myself.
The reason more people don't do it is the effort involved. I'm not aware of any government restrictions on growing it for personal use.
Unless you can come up with a link to back up your claim, the only conclusion I can reach is that you believe that the world simply must be the way you say it is, regardless of a lack of any actual evidence to back up your beliefs.
I did. It isn't hard, but you have to get an early start at this latitude.
I had neighbors comment on those huge (6 ft.), beautiful plants, and ask me what they were, because they had never seen tobacco 'on the hoof' before.
