I was riffing on an idiom and your apparent interest in hemp.

The use of the idiom in this situation would be something like "If industrial hemp production is allowed in the United States, I'll eat my hat.", meaning that you don't think it will ever happen.

So I was joking that if it did become legal, because of your appreciation for the material, at least the hat you would have to eat would be made out of hemp.

That is not what I think.

If there is enough public pressure and people start demanding that hemp production be legal, the laws will change.

As long as a large percentage of the population is fine with hemp being illegal it stands no chance. Most people really don't know what they are missing out on, its not just a drug, it is a very valuable plant that has documented use in human society for thousands of years.
