Well yes it is. Before when local sawmills did lumber, you got a real 2x4. After corporate greed decided they could get more board feet out of a log if they just made them smaller, they SAID it was due to ‘planing and milling’.
I assure you that their industrial machinery can cut more accurately than a local sawmill.
Think of all you’ve learned here about corporate greed and the lies they tell.
Now apply it real life.
