The impedance going to all your neighbors is pretty low too, but I don't think the system relies on signals going out that far and echoing back. High frequencies have more of a transmission line model, which is pretty directional. There's free impedance everywhere.

My understanding is that you mostly care about the minor reflections caused by wire junctions in a system like this, and that line headed outside is more or less a signal sink no matter what. It's possible a capacitor would need to be a bit further away than directly at the breaker box, but by the time you reach the pole I'm reasonably confident that absorbing the entire signal with $.50 of components and no inductor would be fine.

So, let's say that even what you're proposing is correct(which I'm pretty dubious about).

Is your house longer than 32ft/64ft? Those lengths are halfwave on 20m/40m and make a great radiator. For reference all I need is 5w to get out ~400mi so I'm sure these things are kicking off a ton of RF on those frequencies.

Fundamentally if you have an unshielded wire and you're driving these frequencies across it you're going to see RFI along those frequences(along with the harmonics).

Well I have no idea about that part, you'll have to take it up with https://news.ycombinator.com/item?id=15648310

Well I think it's a multifaceted issue, but I am not educated on how your home itself contributes to the radiation profile so I left that bit of speculation out.
