As your frets wear, they become flatter and wider, shortening the distance between the nut and the contact point of the fret. Therefore, intonation problems occur and your tuning method becomes impossible.
The method I use for tuning (it is not my method, I learned it from one of my teachers at Berklee, a guy who played about 400-500 shows a year, and always tuned this way, though he would tune his A string to the piano he was playing with) naturally compensates for the problems of fret wear. The problem with tuning to harmonics is that there is NO TEMPERMENT. You are tuning to a Pythagorean "temperament," which is to say no temperament. This is fine if you are only ever going to play in one key, tune for that key, and are never going to play with any other instruments, ever. It doesn't work in the real world.

Plus your nut
will always keep your guitar from staying in tune as you work your way up the neck. Unless you have the ervana (SP) nut
While I can not dispute the theory behind those things, they are none the less a crock of shit. The nut DOES need to be compensated, but it is not different for each string. They need to be about .010" closer to the first fret than the theoretical intonation point. Well, I (and every other builder in the world) have been doing this for generations. I use a .022" screw slitting blade to cut my fingerboards, using a jig made on a CNC machine (which cuts to the nearest .0001"). This includes the nut location. When I cut these slots, the center of the blade is at the theoretical intonation points for all for the frets, including the nut. The blade kerf is .022" of an inch wide, so my nut ends up being .011" closer to the first fret than the theoretical intonation point. This is close enough, and then some.
The reason most people end up thinking their cool compensated nut, or the Buzz Feitien system, or what ever, makes an improvement is that they go into the shop with a guitar which needs a setup, and when they get it back, the guitar is intonated properly (or at least closer than it was), and so it sounds more in tune. It does not, however, sound more in tune than it would have with just a normal setup, tuned by a well trained ear. I know, I have heard these things side by side, and I have an obsessive ear for intonation. Guitars NEVER sound perfectly in tune, no matter what you do. But a good setup, and a well trained ear, gets you as close as you will ever get.
And yes, I know, I get a little too worked up over this stuff. I just get a little upset when people who are basically con-men try to convince my customers that I don't know what I am talking about in this regard (I am not talking about anyone here). I have an awful lot of experience in this area. I know what I am talking about.
