also cables are shileded to minimize interference..power lines are not and therefore will only increase the EMI and RFI they already geneerate
Phone lines aren't shielded, and most likely generate interference too. The key is to keep the intensity of the RFI low enough as to not cause RFI problems with the majority of the people or to interfere in a frequency spectrum that's not occupied.

Also shielding is not perfect, fittings leak and critters chew on the cable. In other words, shielded cables leak RFI too.

Exactly! Which is why the 5GHz UNII band is the place for this stuff! 5GHz permits interference management through geography.
