As are the dozens of printmakers, papermakers, artists, and bookbinders that I PERSONALLY know, who swear by the superiority of hemp-based papers in EVERY application--from it's ability to take ink and pigments, to it's durability and longevity, to it's ability to be moulded into shapes, forms, textures, and thinnesses that are impossible to achieve with woodp pulp based paper, or nearly any other plant-fiber...
Yeah, you are right. There is simply NO rational reason to use hemp.
Except for the fact that is produces three times the usable fiber per acre that any other fiber plant does.
Or that it produces nearly 5 times the methanol per acre that we can get from corn.
Or the fact that there has NEVER been a single "overdose" recorded in the history of mankind from "marijuana".
Or the fact that hemp ropes and lines are naturally resistant to rotting in salt-water applications, and that is is only surpassed in abrasion-resistance and tensile strength by kevlar-reinforced synthetic line.
