Which is ofc complete nonsense.

Wooden structures allow for a lot cheaper adjustment later on (you usually have a few beams that are structurally important, often its just the outer walls that bear the load). If you try that with stone you can start with hiring an expert upfront or your house collapses.

Same goes energy efficiency. The isolation needs require thick plastic-covers on the outside (for stone), which are prone to mold, birds nests and lead to moss. Every residential stone building in Germany that is older than 10yrs provides you with a prime view through its plaster of where its plastic blocks are assembled, because of the moss. If you don't then they already paid the extra cost of recoating.

Every mortgage issuer will calculate 2-4% extra repair costs for the exterior alone. And we'Re not even talking about the venting, which officially requires a replacement and cleansing every 2-3 years, but of course nobody ever does it.

I could go on for hours about our German stonerism, but will end with the most funny thing, which is that most "stoners" are adamant about longevity vis-a-vis wood, pay extra for the stone, have to wait 3-5 times as long before they can actually move in (drying of mortar and screed can take up to year here in Germany) – but then the most important thing for longevity, the roof, will be made of wood ;-)
