Cellulose in wood is contained in a block of wood, not like the easily accessed strands of cellulose in cotton. It's mixed together with lignin and other components in wood. It is possible to make a weak, brittle kind of paper with straight wood pulp that's mashed and cooked and pressed. Mixing in a little sawdust to rag paper is an old practice. But properly freeing the cellulose requires both extensive mechanical shredding and chemical treatments. As far as 19th century technologies goes it's underappreciated. From what I can piece together, around 1800 in England, a labourer's daily wages would buy a few dozen sheets of paper. By 1900, they could buy literally reams and reams of the stuff.
