isn't that all of the more reason to use a high-resolution 3d LIDAR point cloud - to get the exactly geometry? I hear your point about moving furniture, but you kind of need to do that anyway to get a measuring tape into corners.
Basically, my point is that we'll need all three, and workflow won't be trivial to combine them.
But then you need to measure "free standing" wall (when measuring the opening is not an option), and without someone to hold something flat at the other end for the laser to bounce off, measuring tape still wins.
Which is not to say that laser is not extremely useful: I generally use both.
