I'll add that I don't blame HD, Lowes, et al for the lumber. My grandad would point out that old growth timber was solid and stays pretty straight. New fast growth stuff - not so much. So it is what it is. I have several 2x4s in stock - when I'm in HD I go look and if I see some in a stack that isn't tending to go crossbow I'll grab a few.
Our office is in a large house that was built in 1905. The density and quality of the wood (mostly oak) used in the beams, joists, walls, floors, and the remaining original trim is just amazing.
Part of the flooring is pine, but it's incredibly dense, hard stuff that's far removed from the foamy fast-growing softwood you can get today.
When upgrading the electrics and installing network cabling, we really tried to minimize drilling because that old oak is iron-hard.
Plus, many of the walls are still plaster with actual horsehair, which is somewhere beyond concrete after 100+ years. The only way to cut a hole in that stuff for an outlet or network jacks is with a carbide bit in a Rotozip, and it still took forever.
