Wooden it be nice?

Weaving a fabric would lose the grain pattern unless you simulated one like an Irish sweater, or corduroy.

Vaguely recall someone "melting" wood fibers for printing them

I was thinking it would be more like carbon fiber.

Hemp stalks don't have much of a grain.

Have to trust you on that one, no experience with large overgrown pot plants except for a random hedge growing in Redondo Beach 55 years ago. That had decently large stems from what I recall. Walked by it going to school, didn't notice it until some actual hippies moved in next door and started stripping it. Could have been mugwumps but that would be splitting hairs.

Same as with Bamboo. It's a stalk not a trunk, you might be able to press them together but not to get dimensional lumber.

Weaving the fiber would eliminate the anisotropy.

Have seen bamboo "lumber" 2 x 4s replacements at the local orange or blue store. Looks like lightly stained semi prefinished wood. Don't know if it was structural or decorative or even rated for outdoors. Can't see why they couldn't engineer it appropriately.

It's all fun and games until you get ship worm on your land yacht.

Bamboo might be a good option, as it grows quite easily, and can be effectively cheaper to use as a plywood feedstock.
