Wood is nature's bug food. There are armies of creatures ready to turn any fallen tree into compost. A plank or joist is just nature food with the bark removed. Wood is OK for use in deserts, where there's no water, or in sub-zero climate, in either case most lifeforms won't survive. But in our green and pleasant land, wood is just compost-to-be.
Almost every old building you see is stone or brick. Not because they didn't use wood back then, they built lots. But because those they did build haven't survived.
It's a DIY forum. Get a breaker bar, pull it down and take it to the tip. Don't sit in a chair and complain that someone else wants money to do the stuff you could do.
