Totally agree. I sometimes snatch up discarded furniture just for the wood. My wife complains, but I convince her that solid wood is worth it. Most of the stuff discarded is the man-made pressed sawdust stuff. A neighbor of mine offered me a "solid-wood" desk and cabinet, I showed him that it was laminated plastic over pressed-wood. Lots of people don't know the difference! I recycle the real wood, rout connecting edges, glue and press them with clamps to make wider pieces and plane them smooth, then make furniture from them. As you say, they'll last multiple lifetimes (daughters plan on passing on furniture I made, to their children when they grow up).
Apple content: same can be said for Apple products, they have higher resale value than the other stuff out there. Writing this on a used Mac Mini I bought from someone else who upgraded. Used Apple stuff has a long life for many purposes versus the other stuff.
A large portion of our furniture was solid wood purchased at various auctions and refinished. Like you say, it’s so much better than flakeboard. Years ago my with accidentally spilled nail polish remover on a piece of “wood” furniture we’d bought. Not only was the grain phony but the wood was phony. Never bought anytging except solid wood since.
