Would you be so eager to rip apart walls if they were plaster and
lath?


If it were my home and I was rewiring it, I would want the wires to be
concealed. And I would want to do it right and to code. So no problem
tearing apart the walls if it was needed. I've never been afraid of work.
But that is me.

Also note that I have a lot of other wires for TV, Satellite, Stereo,
Computer, etc. So it is going to look really tacky to run all these exposed.
