"carbon negative" isn't BS: since the CO2 already sequestered in the wood remains there (mostly), while the trees cut down for that wood are replanted eventually capturing more CO2, thus ultimately removing more CO2 from the atmosphere than was released through the sourcing of the wood.
Now considering everything involved in the building process, the house as a whole is probably not "carbon negative" -- and perhaps that's your objection -- but when it comes to the primary material (wood vs concrete/steel) it can be carbon negative.

There are few wrong assumptions with your statement:
1) The wood the house is built with will not be there forever, some day the house will be torn down and the wood burned or rotten
2) Cutting down trees and planting new ones is not a good way of carbon sequestration. Otherwise, why not cut down all trees and just plant new ones? Bam, carbon negative, climate problem solved.
People need to understand that trees should not be seen as a renewable resource in the context of climate change. Not for building, not for burning as fuel.
