So one can install a D8R035TIA kit for $122 MSRP plus labor if they are not a authorized shop, then the market value (presumptive sale on eBay) of their 035TIA is cost plus labor plus nominal core value. I'm not so sure about that. Or install a C8R2245H for $270 plus labor plus $70 core value and that makes their 2245H worth how much?

Well, somebody is going to have to make some objective determinations sooner rather than later. (See prior post.) With the price of the aftermarket 033 diaphragm on eBay (which I will admit is a bad sign to begin with), there isn't that much cost involved. If one is deeply involved in this hobby and has the proper equipment along with the inclination, $35 - $40 ain't squat. And it seems as though all of your argument is subjective. Not saying your particular experiences were not determinative for you in your instances, but not all situations present the identical set of facts from which conclusions should be drawn.
Please believe me here. I'm not trying to offend anyone, just attempting to have a reasoned, rational discussion of the issues that confront us all. With 12 or so (depending on how you count) pairs of JBL speakers, most vintage, and a room full of spare parts I have a vested interest.
