FYI, you constantly charge that houses with K&T have ONE outlet per
bedroom. This is pure nonsense. The original wiring was very sparse but
virtually all the houses with K&T that I've worked in have added new
circuits, outlets, central air, breaker panels, etc. over the years,
just like houses built post K&T have done.-

you point out part of the problem....... how many of those changes
were done properly?

most were likely piecemeal low cost changes as demoed from the photo
by the OP.

and the OPs homew may be full of such hazards buried in places they
cant be seen
