My house was built in 1929 using old growth lumber by somebody who didn't know how how strong to build things, and it was overbuilt so much I could park a tank in my living room.
Literal tree trunks for beams that are so dense I can't pound a nail in to them. The "2x4s" for framing walls measure 3inches x6 inches. The subfloor isn't thin plywood, its 3x12 inch planks

On the other hand, one old house I lived in needed concrete floor support jacks in the crawl space because the floor joists were too weak on their own. They just didn't have standards and building inspectors back then.
On the other hand, when I renovated, I found the wall studs were actual 2x4s, not 1.5x3.5 like modern ones. But they were rough cut, right from the sawmill.

2x4 refers to the rough cut dimensions, so that's why. Modern studs are "finished 4 sides", which decreases the dimensions after rough cut.
