Len, I've considered the same thing and even gone so far as to use a meter to check continuity between the tank and the anode. I've never found a discontinuity. It goes to my earlier reply that these "sealants" are not actually supposed to seal pipe joints. What they do is lubricate the threads and allow the joint to be tightened further than without. The seal ultimately comes from the metal to metal contact between the two pieces. One could argue that the sealant packs into the interstitial spaces of the threads and lands - and it may if too much sealant is used or the joint is not tightened enough - however, a leak tight connection is almost always achievable without lubricant or with even the lightest weight lubricant. It is also within reason to argue that certain lubricants/sealants limit/eliminate corrosion and thus facilitate removal of the fitting in the future.
As stated before, I've had more fittings leak because of too much sealant/Teflon tape then because of too little.
