One question, when re-wiring an outlet, for instance to replace the old
useless Romex with clipped grounds, with fresh new 12/2 - how do you tell
where the wire goes? I mean how do you tell without hacking chunks out of
the wall?
In my house it looks reasonable that the Romex goes from the attic and drops
down to the outlets, so in this case it would be stapled to the studs going
up - but what's the easiest way to determine that without major destruction
of the wall? For all I know it could be threaded through the studs (or
worse in front of the studs as was done in a few spots). I guess you could
use a stud finder or the like, but old Romex is pretty heavily shielded and
it'd be easy to lose the run among the studs.
If I'm looking at demolishing the wall, I might as well remove the entire
wall in one sheet - at least then I can put up insulation while I'm there
and clean out the buggies.

Depressing news: In my previous house, built in the 1940s, the Romex was
stapled every which way. Goodbye, walls, at least for the part I rewired.
But, when we got estimates for redoing the kitchen, 3 electricians said they
were comfortable snaking new wires in existing walls, even though it meant
the wires couldn't be fastened to the studs. How they expected to do this, I
have no idea.

If you are replacing your romex because it has no grounds, there are
2 ways to fix this without snaking new wires. You can put a GFI
outlet on the first outlet of the circuit, which then protects
anything downstream of the outlet, or you can protect the entire
circuit with a GFCI breaker. In most jurisdictions, code permits this.
You are protected against shocks.

Well I guess that's an option. In that case I'd only have to do the outlets
and the panel.
Both responses that I've heard so far, yours included, tell me that I'd
either get used to GFCI outlets or break out the crowbar and start knocking
holes. If it comes to knocking holes, I'm replacing the whole drywall sheet
and putting up the insulation might as well kill 2 birds with one stone.
I'll also probably halt my painting, no sense painting the walls if I have
to rip it out anyway.
I so much want to do this the "right" way, and not fall back on GFCI
outlets - but time and money talks.

Sheetrock is cheap, and the insulation will pay for itself quickly. As you
said, time's the issue. But, with home projects I've never done before, I
find that once I figure out how to do things efficiently, the second room
usually goes quicker than the first. Usually.
